Costco Wholesale is a favorite among shoppers nationwide thanks to their buy-in-bulk format and beloved Kirkland brand. But, depending on your circumstances, not everything from this retailer, which is the second most-popular grocer according to Dunnhumby’s second annual Retailer Preference Index (only falling short to cult-favorite, Trader Joe’s), is worth a purchase. For example, unless you’re buying for a party or a large, hungry family, some perishable items might not make sense to buy by-the-pound. But, no matter who you are, there are some items that are undoubtedly worth getting that yearly membership for. After vetting some tried-and-true Costco lovers, we’ve rounded up pantry and freezer staples you shouldn’t be purchasing anywhere else.

The price and amount of this chicken might seem alarming, but when broken down by the pound, buying meat at Costco is actually a great deal. And since you can easily freeze chicken, you don’t have to worry about your precious poultry going to waste. Another crowd favorite from Costco is the rotisserie chicken, which famously retails for just $5. This product became so popular, the company opened its own production facility just for the rotisserie chicken back in 2018.
Food Network staffers can't get enough of Costco's sheet cakes — and for good reason. Get a full sheet cake for a special event (one staffer even had it at her wedding!) or opt for a half-sheet for a smaller event. Either way, you'll ensure a delicious cake with an impressive frosting.
A lot of shoppers praised the quality of Costco’s EVOO. And if you’re regularly dressing salads or using olive oil in your cooking, stocking up is probably a great option. Don’t be intimidated by the two-liter bottle. We recommend this handy oil dispenser to make portioning a breeze.
If you’ve come to accept the notion that nuts are expensive and that is that, well, we have some great news for you. Kirkland has a huge variety of mixed, salted and unsalted nuts at competitive by-the-pound prices. Never think twice about adding this protein-packed snack to your cart again.
Some whole spices can stay fresh for up to three years, which means buying in bulk at a discounted price is definitely worth it whether you’re going to use those seasonings every day or a few times a month. Be strategic, though. Ground spices can start to lose their flavor around six months, so only pick up the ones you know you’ll use often (like salt and pepper!).
Paper goods are something you’re probably already buying in bulk, so why not get them at a great price at Costco? Those who love the retailer stock up on kitchen essentials like paper plates, paper towels and napkins because they know there is nothing worse than reaching for a paper towel and realizing, you’re out.
In-Store Only Items You Need
We wouldn't be doing you any services if we didn't share must-buy items you can only buy in-store. Other products Costco superfans swear by are Kirkland-brand vanilla extract (one of our editors has a bottle in her pantry at all times!), wine (seriously, who doesn't want a mega-bottle of rose?) and frozen fruit (smoothies, anyone?).
