Worst Things to Buy at Warehouse Clubs (Costco, Sam's Club, BJ's)

When time is short and your shopping list is long, it can be tempting to make a single stop at the warehouse club. After all, Costco, Sam's Club and BJ's stock everything from groceries and cleaning supplies to electronics and clothing - often in bulk quantities and often at discounted prices. Plus, you need to get your money's worth from the annual membership fee you're paying. Smart shopping move, right? Not necessarily.

While many warehouse club deals are, indeed, good, you might want to skip over certain items. There are three big reasons. One, buying in bulk doesn't make sense if you don't need bulk quantities or you won't use them up before they spoil or expire. Two, quality isn't always up to snuff at warehouse clubs. And three, you're missing out on the money-saving power of weekly sales and coupons -- Costco and Sam's Club don't accept manufacturer coupons; BJ's does, but with restrictions.

Here's a look at 16 common items stocked by warehouse clubs that you might want to pick up somewhere else.

Name-Brand Cereal

Warehouse clubs stock name-brand cereals, but budget-conscious shoppers know they can grab the breakfast staple for less elsewhere. Kellogg, General Mills and other cereal manufacturers regularly offer discounts and coupons that can be used at your local grocery store or big-box retailer - but not at Costco or Sam's Club -- says Cindy Livesey, founder of

Look for these coupons in your Sunday newspaper or on the manufacturer's website or Facebook page. Also, you can stack these coupons with any sale your local retailer is promoting. "This allows you to get a better deal at the grocery store than what you'd find at a warehouse club," she adds. For example, a recent weekly sale promotion at Target featured a "two for $7" deal on select cereal brands including a 24-ounce box of Kellogg's Rice Krispies. On Kellogg's website, you can print out a coupon for $1 off on two boxes of Rice Krispies. So, you could buy two boxes at the big-box retailer (48 ounces total), plus get a dollar offer with the coupon, which drops the sale price to $6. That amounts to about 12 cents per ounce -- two cents cheaper per ounce than what we saw at a warehouse club.

Designer Clothing

Don't be fooled by the discounted prices you might see on designer clothing items (think: Nicole Miller, DKNY or Calvin Klein) at Costco, Sam's Club or BJ's. "These items are not the same high-end items you can buy directly from the manufacturer or at high-end retailers," warns Kristin McGrath, an editor and shopping expert for The designer clothing and accessories you'll find at warehouse clubs are typically constructed using lesser-quality materials and are designed specifically for lower-tier retailers, she adds.

If you're simply on the hunt for a basic t-shirt or pair of jeans and don't care about labels, warehouse clubs will offer competitive prices, McGrath says. Just keep in mind that you aren't getting a bargain deal on the same pair of designer jeans at Costco that you'd find at Neiman Marcus.

Skincare Products Containing SPF

Err on the side of caution when purchasing skincare products containing SPF from a warehouse club. That's because SPF degrades over time and Costco, Sam's Club and BJ's usually sell these types of items packaged in sets of two large containers, warns smart shopping expert Trae Bodge. Before buying, you should consider how often you'll use the product and if you'll be able to use it up before the expiration date.

Skincare products containing SPF have a shelf life of up to two years, if stored properly, according to However, if you're only applying a thin layer of product each time you use it, it can take longer to finish, the site notes. Unless you frequently use these types of skincare products or are sharing them with someone else (say, your spouse), you may want to steer clear of buying them in bulk, Bodge says. You're better off purchasing a regular-size version (about 6-ounces or less) from your local drugstore, where you can take advantage of weekly sales, coupons and loyalty discounts. You'll get your money's worth, since you should be able to finish it before it's time to toss it out.

Ground spices have a shelf life of two to three years for peak freshness and flavor, according to manufacturer McCormick. If you're buying standard-size spice bottles (which usually range from 0.6 ounces to 3 ounces at a traditional grocery store or big-box retailer), finishing them within that timeframe is realistic. However, when you buy spices in bulk at warehouse clubs, which can range in size from 4-ounce bottles to 5-pound containers, it can take much longer -- especially, if it's a spice you don't frequently use, says smart shopping expert Bodge.

While spices don't "go bad" the same way that perishable food items do, they do lose their potency over time, she adds. So that cinnamon apple pie you make every summer that everyone looks forward to at the family reunion may not be as flavorful if you're using a bottle of ground cinnamon to season it that's several years' old. With that said, unless you regularly cook with certain spices, Bodge recommends buying them from your local grocer in regular sizes so you don't end up wasting your money later.

For families with young children, shopping at a warehouse club can offer huge savings. But defaulting to Costco, Sam's Club or BJ's without doing your due diligence could cost you -- and this is especially true when it comes to diapers and baby supplies.

We looked at prices for store-brand diapers (in size 3) at Costco, Sam's Club, BJ's and Target. Here's what we found: At Costco, a 198-count package Kirkland Signature Supreme diapers costs $35.99 (about 18 cents per diaper). At Sam's Club, you can get 234 Member's Mark Comfort Care diapers for $39.84 (17 cents). At BJ's, a 180-count package of Berkley Jensen Ultra Absorbent diapers totals $25.99 (14 cents). By comparison, at Target you can get a 222-count box of Up and Up diapers for $28.99 (13 cents). Based on unit price, the big-box retailer offers the better deal.

When looking for deals on other baby supplies, such as wipes and diaper ointment, consumers can score big using Amazon's Subscribe and Save program,'s McGrath says. The program allows parents to set up auto-delivery on everything from lotion to hair-care products for kids. Amazon Prime members qualify for 20% off diapers and other related products when ordering at least five items per month, she notes. "You can even skip a delivery if necessary or you need to change diaper sizes. You're not committed to the size on a giant box of diapers you purchased in bulk a month ago at a warehouse club," McGrath adds.

Shopping at a warehouse club can help you save big on a variety of kitchen staples, but there are a few you should consider buying elsewhere. This includes soda and other soft drinks. Consumers can pick up these same items at a traditional grocery store or big-box retailer at cheaper prices when shopping their weekly sale promotions, says's Livesey.

At a Washington, D.C.-area Harris Teeter location, we spotted a buy-one-get-one-free sale on a 12-pack of 12-ounce cans of Canada Dry Ginger Ale (regularly $7.49 each). That amounts to 24 soda cans. At Sam's Club, a 24-pack of the same size cans of Canada Dry Ginger Ale cost $7.58. That's nine cents more than Harris Teeter's BOGO deal. A weekly sale promo at a D.C.-based Lidl location included a 12-pack of 12-ounce cans of Lidl's store-brand sparkling water (the packaging was very similar to La Croix's) for $2.69 each. At Costco, a 24-pack of La Croix sparkling water totaled $8.59. You could purchase two 12-packs from Lidl for $5.38. That's over $3 less than at the warehouse club.

Liquid Cleaners

Liquid cleaning products tend to lose their efficacy over time. So, storing huge bottles of liquid dish soap or laundry detergent for months on end may not be a smart money-saving strategy after all -- especially, if you end up having to use twice the amount of product to get the desired result with a single wash. "Unless you do a lot of laundry [or wash dishes by hand] very regularly, it is best to buy liquid detergents in smaller quantities," smart shopping expert Bodge says.

If you prefer to shop exclusively at warehouse clubs rather than making multiple trips to several stores, consider buying powder-based cleaning products instead, Bodge recommends. When stored properly in a cool and dry place, they have an unlimited shelf life.

Seldom-Used Household Products

Before stocking up at warehouse clubs on household products you only need infrequently, consider the size of your home, McGrath suggests. Buying carpet/upholstery cleaner, plumbing clog remover, air freshener and other seldom-used products, either in multi-packs or in large containers, will just take up valuable storage space underneath your kitchen or bathroom sinks, she adds. You might even forget you stored them there and end up not using them for months at a time, if at all. For everyday shoppers, big-box retailers are the better option for purchasing these types of household products in smaller quantities, McGrath advises.

Printer Ink

We've all been there: You're rushing to print out an important document at home only to discover that your printer is out of ink. Frustrated, you make a mental note to pick up one of those bulk-size packages of printer cartridges on your next Costco run.

While warehouse clubs offer loads of deep discounts on computer accessories, you may want to skip buying bulk printer ink cartridges, says Joanie Demer, co-founder of That's because with some online research, you can find even cheaper deals from other retailers.

For example, we spotted a two-pack of Brother's Innobella ink cartridges (each pack contained three color ink cartridges) selling for $49.99 on Costco's website. On Amazon, a single pack of the same printer cartridges costs $19.98 (or $39.96 for two packs, so $10 cheaper than It's important to note that when purchasing ink cartridges or similar products from Amazon, be sure they're sold directly by the e-commerce giant and not by a third-party seller. This helps ensure authenticity.

Over-the-Counter Medicine

If you've ever suffered from an unexpected headache only to discover that you're out of ibuprofen (Advil) or acetaminophen (Tylenol), stocking up on a bulk-size bottle of pills during your next warehouse club trip may seem like a smart idea. Keep in mind that unless you have a medical reason to use such products on a daily basis or multiple people in your home are using them, you may not get though that entire 750-count bottle of pills that you picked up at BJ's before they expire, warns consumer savings expert Andrea Woroch.

Should you consider using pain meds beyond the expiration date stated on the bottle, note that they can lose potency over time. This can make them less effective per the recommended dosage. In fact, Advil recommends consumers stop using any expired bottles of their products for this very reason. With that in mind, you can save big by purchasing smaller containers of generic Ibuprofen or acetaminophen from a drugstore or a big-box retailer, Woroch says.

Dips and Spreads

Like to keep your pantry stocked with snacks for binge-watching your favorite Netflix series? Then you may be enticed to buy that huge tub of hummus or artichoke dip at your warehouse club of choice. Yes, you get more for the money. However, will you have eaten that entire 40-ounce container of hummus by the time you're done watching the new season of "Orange Is the New Black" in just two days? Probably not.

Unless you're buying food for a party or have a large family, you should only buy refrigerated hummus, cheese dip and salsa in smaller quantities, consumer savings expert Woroch recommends. That's because these are perishable food items that go bad after a specified amount of time once opened. For example, the packaging on Sabra brand hummus containers includes a disclaimer that states it should be consumed within seven days after opening.

While you may end up spending more at a traditional grocery store or big-box retailer when you factor in the unit price, you're more likely to finish the smaller container. And if you're dead set on scoring a deal, pay attention to weekly sale ads at places such as Trader Joe's, Target or Walmart, which regularly offer discounts on chip dips and spreads, Woroch notes.

Canned Goods

If the Apocalypse ever happens, those 6-pound cans of beans you've got stashed in your kitchen pantry may come in handy. Otherwise, you're better off buying regular-sized canned goods from your local grocery store that you'll actually finish, suggests Livesey of Some grocers even offer exclusive deals on canned items at various times of the year when prices are slashed, she says. According to the Canned Food Alliance, canned goods can last up to two years after the date of purchase, so shoppers can stock up in moderation with these sales.

Livesey notes that at ShopRite grocery stores (located in Connecticut, Delaware, Maryland, New Jersey, New York and Pennsylvania), the chain offers a two-week-long sale known as the "Can, Can Sale" twice a year. It includes deep discounts on canned goods and other kitchen and household items. She also notes that Kroger, a national grocery chain, hosts "Mega Event" sales that require shoppers to buy a certain amount of select items in order to get the discounted price. For example, one of their recent sales included a deal on canned organic tomato sauce, as mentioned on Regularly priced at $1 per can, the sale dropped the price to 50 cents each when you purchased at least six cans.

If you're planning to stock up on chicken, beef or seafood during your next warehouse club visit only to stash it in the freezer when you get home (with no immediate plans to use it), reconsider. Unless you're prepping for a large family gathering or have a house full of kids, there's a good chance you might forget it's even there,'s McGrath suggests. And, by the time you do remember that four-pound bag of tilapia may be covered in freezer burn and you'll have to throw it away.

There's nothing wrong with stocking up on meats you cook regularly -- especially if you like to meal prep. However, do so in smaller quantities at your local grocer, McGrath recommends. You'll be less likely to overbuy. Also, be sure to keep out an eye out for weekly sales at your favorite grocery chain or coupons in the Sunday paper. For example, at Washington, D.C.-area Harris Teeter locations, we regularly see buy-one-get-one-free deals on packages of sausages, bone-in chicken breasts, pork tenderloins and spare ribs.

Fresh Produce

Fresh fruits and vegetables can be pricey -- especially, if you're buying organic versions from specialty supermarkets. Warehouse clubs offer a variety of organic options, and oftentimes they cost around the same price as what you would pay for smaller amounts elsewhere. For example, at Sam's Club a 32-ounce bag of organic green beans sells for $5.48 (about 17 cents per ounce) compared to $5 for a 16-ounce bag (31 cents per ounce) at Whole Foods. Based on the unit price alone, the warehouse club seems like a no-brainer.

But before you plunk down your hard-earned cash on a bulk-size bundle of fruits and veggies, ask yourself some questions first, says Bodge. How many people in your household will eat those items? Will they be able to finish them before the produce starts to go bad after a few days? If you answered no to the latter question, your money is better spent buying the smaller package you can actually finish versus having to toss half the container because it's spoiled.

Kirkland Signature Facial Tissue

Many of Costco's Kirkland Signature products have been lauded for their quality and affordability compared to name-brand versions. However, some of the warehouse club's store-branded items can fall short of expectations, suggests's Demer. She specifically calls out the quality of Kirkland Signature facial tissues, which Demer claims don't last as long as other brands. "I use them up fast . . . and spend more money to refill them sooner," she says.

You can find deals on better-quality facial tissue at big-box retailers compared to what you'll get with Costco's private-label version, Demer notes. For example, you can buy three 3-packs of Puffs Plus Lotion 2-Ply Facial Tissues, which contain 372 sheets per pack (that's 1,116 sheets total), for $14.07 at Target. At Costco, a 12-pack of Kirkland Signature 2-Ply Facial Tissue, which contains 1,080 sheets total, rings up for $14.29.

Almost Anything You Buy on Impulse

If you visit Costco, Sam's Club or BJ's on a random Saturday or Sunday with an empty stomach, you'll probably walk out feeling stuffed. That's because they all offer free food samples that you can enjoy as many times as you want. Members can score sample-size versions of everything from mini quiches to pot stickers. While this is a tasty perk, warehouse clubs are hoping you'll like these free goodies so much that you'll impulsively toss a bulk-size package or two into your shopping cart.

But if you do, warns's McGrath, "this becomes a much bigger investment than your average grocery store impulse purchase." Not only will you need to find space in the freezer or cupboard to store your bulk purchase, but if your family ends up not liking that 48-count box of snack bars you bought on a whim, you may never finish them by yourself, she notes.
