There’s a moment every Costco member knows well. You push that oversized cart through the doors, and suddenly $300 has vanished like it was nothing. But here’s the real question: was it actually worth it? Not everything at Costco is the bargain it looks like, and a few items are genuinely among the best deals on the planet. The trick is knowing the difference.
Some purchases at Costco make so much financial sense that it would almost be irresponsible to buy them anywhere else. Others? They look great on the shelf, but the math just doesn’t hold up once you get home. Let’s get into it.
1. The $4.99 Rotisserie Chicken – An Unbeatable Deal That Defies Logic
Let’s be real, there is no better food deal in all of retail right now. As of early 2025, the price for a standard rotisserie chicken at Costco in the United States is still $4.99, a price that has been consistent since 2009. That means it has survived inflation, a global pandemic, supply chain chaos, and just about everything else the world has thrown at it.
Costco revealed to its investors that it sold 157.4 million rotisserie chickens worldwide in fiscal year 2025, equivalent to over 431,000 every single day. The numbers are staggering. It’s not just a chicken. It’s a cultural institution.
The chicken is the very definition of a loss leader – a product that a store sells at a super low price, usually less than what it costs to make, in an effort to get more foot traffic. The idea is that if you come in for that great deal, you’ll stay and add other things to your cart. Costco basically pays for the privilege of feeding you well.
2. Kirkland Signature Organic Extra Virgin Olive Oil – Certified and Genuinely Legit
Most olive oils at the grocery store are quietly lying to you. Diluted, mislabeled, nowhere near the quality they claim. Costco’s Kirkland version is different. The Kirkland brand extra virgin olive oil is Bureau Veritas certified and confirmed as legitimate extra virgin olive oil in a study by the UC Davis Olive Center. That matters enormously in an industry riddled with counterfeits.
After testing a range of olive oils from the Kirkland Signature lineup, Daily Meal found that the organic extra virgin variety stood out as the winner, with its balance of exceptional taste and affordability making it a standout even for serious foodies. For a 2-liter bottle, it’s roughly a fraction of what comparable certified oils cost elsewhere.
Kirkland Signature Organic Extra Virgin Olive Oil is one of the few imported oils that actually meets international and U.S. standards, while other brands are often diluted with cheaper oils and have problems with quality and flavor. Honestly, this is one of those Costco purchases that makes you feel clever.
3. Kirkland Nuts – Walnuts, Almonds, and More
Nuts are one of those categories where buying small is basically throwing money away. Costco’s Kirkland Signature Almond Butter comes in at $0.22 per ounce, while the same product at Walmart costs $0.42 per ounce. You can plan to save around 56% when you buy your walnuts at Costco instead of Walmart. That is a genuinely massive difference, not some marginal saving.
Kirkland nuts, particularly walnuts, are a standout deal – the Kirkland brand walnuts work out to just $2.66 per pound for a three-pound bag. If you snack regularly or cook with nuts often, the Costco math here is essentially a no-brainer.
4. Frozen Organic Produce – Stock the Freezer, Save the Budget
Here’s the thing about fresh produce at Costco: proceed with caution. But frozen? Completely different story. Frozen produce is very popular at Costco, especially broccoli. A four-pound bag of frozen broccoli costs just $6.99. It’s convenient to keep in the freezer for healthy dishes, and it saves money because it lasts a long time and is cheaper than buying fresh every time.
Frozen items from Costco are definitely the way to go if you have space in your freezer. You won’t experience as much food waste, and you can stock up when there is a big sale. Organic frozen blueberries in particular are a remarkable deal per pound compared to most grocery stores.
5. Kirkland Organic Honey – Bulk Sweetness That Makes Sense
Organic Kirkland honey is priced at three bottles for $12.49, working out to just $4.16 per pound. Compare that to specialty grocery stores where a single decent jar of organic honey regularly runs eight to twelve dollars. The savings here are significant for anyone who actually uses honey regularly in cooking or tea.
No kitchen is complete without honey, and Costco is an ideal place to find a three-pack of raw honey available for $14.99. It’s a pantry staple that keeps for practically forever, which makes the bulk format completely logical.
6. Oat Milk – A Surprisingly Smart Buy
Milk alternatives are one of those categories that can quietly wreck your grocery budget. A single carton of oat milk at a regular store can cost four or five dollars. Buying milk alternatives can get very pricey, but Costco’s lower prices make it a great spot to buy oat milk. The oat milk is extremely creamy and sweeter than almond milk, and Costco offers a case of six 32-ounce containers for just $11.49.
That works out to less than two dollars per carton. For anyone who uses oat milk daily in coffee or cereal, this alone can justify a significant portion of the annual membership fee. It’s simple math that adds up fast over a year.
7. Kirkland Protein Shakes – Gym Value That Holds Up
Protein supplements are notoriously overpriced at specialty health stores and even online. These protein shakes are ideal for gym-goers and people who live on the go. For only $36.99, you can get an 18-pack where each one comes with 30 grams of protein. That’s a genuinely competitive price per serving compared to most branded alternatives.
Kirkland accounts for nearly a third of all Costco sales, generating over $86 billion in 2024 alone. The sheer scale of that private-label operation is part of why the prices stay so competitive across the board. When a brand sells that much, it can afford to keep margins razor thin.
8. Basmati Rice – The Bulk Staple That Actually Wins
Rice is the definition of a pantry workhorse, and bulk buying rice is exactly the kind of purchase Costco was built for. The 20-pound bags of Basmati rice are cheapest at Costco. You’ll save $1.69 per bag and $0.09 per ounce if you stock up at Costco versus Walmart. Small per-ounce differences sound trivial, but when you’re talking about 20 pounds of rice, they compound meaningfully.
Rice doesn’t expire quickly, it stores easily, and you’ll use it all eventually. It’s almost the perfect bulk item. Think of it like buying a really long runway for your dinner plans – no urgency, no waste, just consistent savings over time.
9. Snack Packs and Variety Boxes – Practical and Underrated
Another great thing to buy at Costco is snack packs in bulk. The store offers all kinds of affordable mega variety packs that are perfect on the go and ideal for adding to children’s lunches every day. Having these non-perishable items in the pantry is a huge time-saver.
Chips, pretzels, cheese curls, and salty-sweet bark can run up a big bill especially if you buy small single-serve packs. Buying snacks in bulk at Costco saves serious money, as well as the time spent parsing out servings from larger packages. For households with kids especially, this one pays off every single week.
RIP-OFF #1: Fresh Produce in Large Quantities – Almost Always a Mistake
Will you really go through 10 pounds of potatoes before they start sprouting? How about 17 bananas? If you have to throw out some of every large bag of produce you buy, you’re not really saving money. Stay away especially from lettuce, spinach, and other delicate leafy greens unless you have specific plans for them immediately.
Per pound, Costco prices on produce are often actually more expensive than other grocery stores. Costco’s pineapple was $3.99 each, outpricing both Fred Meyer and Winco’s recent deals. The combination of higher prices and higher waste risk makes fresh produce a genuinely poor Costco purchase most of the time.
RIP-OFF #2: Bulk Beauty Products – They Expire Before You Finish Them
This one catches people by surprise. A giant tub of moisturizer looks like incredible value until you realize it’s gone bad six months later, barely half-used. Several beauty items typically have a lifespan ranging from six months to one year before reaching their expiration date. It’s crucial to consider whether you’ll be able to use the product within this specified timeframe. Face creams and sunscreen, for example, can expire or lose their efficacy before you’ve been able to finish them.
It’s hard to say for sure exactly which products you’ll burn through fast enough, but the rule of thumb is simple: if you don’t use it daily, don’t buy it in bulk. A bargain that expires in the cabinet isn’t a bargain at all. It’s just slow-motion waste with a good price tag.
RIP-OFF #3: Canned Goods – The Math Often Doesn’t Add Up
This one surprises most people. Bulk canned goods feel like the ultimate smart buy, but the reality is more complicated. Cases of canned goods at Costco often work out to more per can than items at the grocery store. For example, canned tomatoes at Costco priced out to $8.89 for eight cans, or $1.11 per can. Regular grocery store sales routinely beat that price.
If you’ve been buying canned goods in bulk at Costco because you assume it’s cheaper than a grocery store, think again. Like canned goods, the regular sales at grocery stores on major brand name items often drop the price per ounce much lower than Costco’s price. Patience and timing at a regular store will almost always beat Costco on canned goods.
RIP-OFF #4: Kirkland Cold Brew Coffee – One of the Most Complained-About Products
Cold brew coffee is supposed to be smooth, bright, and easy to drink. Costco’s canned version has a very different reputation. Kirkland Signature Colombian Cold Brew Coffee is one of those products that Costco customers actively warn against buying. Its taste has been compared to the dregs you’d get at the end of a coffee pot. That’s a pretty damning description.
The lengths to which Costco customers actively go to avoid drinking Kirkland Signature Colombian Cold Brew Coffee once they’ve bought it are quite wild. One person mentioned that it took them several months to get through a case, and they’d only drink it when there was nothing else available. When you’re buying in bulk, that kind of buyer’s remorse hits differently. Skip it and buy a better brand – even if it costs slightly more per can, you’ll actually finish it.
Final Thought
Costco is genuinely one of the smartest places to shop in America, but only if you know what you’re doing. The wins are real, from certified olive oil to a loss-leader chicken that has somehow stayed at $4.99 for over two decades. The losses, though, are just as real: beautiful produce that rots by Wednesday, beauty creams that expire quietly in your bathroom, and canned goods that grocery store sales regularly beat.
The membership is worth it, but the magic is in the strategy. Buy what you’ll actually use, in quantities that make sense for your household, and skip the items where Costco’s bulk model works against you rather than for you.
