Costco built its reputation on two things: cheap hot dogs and the promise that you're always getting a deal.
But a closer look at the warehouse giant's newer promotions shows something less flattering.
Some of the so-called savings are engineered to make you spend more, not less — and the math only works if you're paying attention.
Costco raised annual fees in September 2024, bumping Gold Star from $60 to $65 and Executive from $120 to $130.
The company frames the Executive tier as a no-brainer because of its 2% annual reward.
But that reward only pays back the extra $65 if you spend roughly $3,250 a year — about $271 a month.
Plenty don't, and they're quietly subsidizing the ones who do.
Costco deliberately rotates inventory and parks limited-time items in high-traffic aisles.
That's not a coincidence; it's a strategy.
Those "while supplies last" deals on patio furniture, vitamins, or a 12-pack of something you didn't know existed are designed to trigger a buy-now reflex.
The coupon book deserves its own scrutiny.
Costco's monthly "Instant Savings" booklet looks like a stack of coupons, but most discounts are already baked into the shelf price by the time you walk in.
You're not clipping anything — you're just being shown a lower number next to an inflated original.
It's also why the "was" price on the tag is worth a skeptical squint.
Bulk pricing isn't automatically cheaper either.
A 2024 analysis by Consumer Reports and other shopping researchers has repeatedly found that unit prices at warehouse clubs beat supermarkets on some staples and lose on others — especially produce, which spoils before a small household can finish it.
Buying 36 eggs at a great per-egg price is only a deal if you eat 36 eggs.
Otherwise you've bought expensive compost.
The return policy is the genuine bright spot.
Costco's generous returns — including its 100% satisfaction guarantee on most items — give you a real safety net, and the company honors it without much friction.
That's a legitimate reason to shop there.
It's also a reason the company can afford to be aggressive elsewhere: the goodwill keeps members loyal through fee hikes and impulse buys.
Its business model depends on annual fees, high-volume turnover, and members who treat a trip as entertainment.
None of that makes Costco a scam — it's just a store optimizing for its own numbers.
The question is whether you're optimizing for yours.
The takeaway isn't to cancel your membership.
It's to walk in with a list, check unit prices against your actual grocery store, and treat the treasure hunt as a marketing tactic rather than a treasure.
It can also be a $300 Saturday you didn't plan for.
Final Thoughts
The difference is whether you're the one running the numbers.
