Which One Is Actually the Cheapest?

You’re standing in front of a giant wall of toilet paper, trying to figure out if you’re actually saving money or just paying for the privilege of buying a lifetime supply.

Most people treat warehouse clubs like a religion, but let’s be real: they’re businesses designed to get you to spend. If you’re looking for the absolute lowest price, you’ve got to look past the rotisserie chicken and do the math.

It’s easy to get swept up in the hype of a $1.50 hot dog, but that doesn’t tell you much about your monthly grocery bill. To find the real winner, we have to look at the cover charge just to get in the door and what you’ll pay for supplies. Here’s how the big three stack up.

The price of admission

Before you can even touch a bulk-sized bag of frozen berries, you’ve got to pay for the right to shop. If you’re looking strictly at the entry fee, there’s a clear hierarchy.

1. Sam’s Club: This is the budget leader. Its basic Club membership costs $50 a year. But honestly, you shouldn’t ever pay full price for this. Sam’s Club is famous for running promotions that drop that price to $25 or even $20 for new members.

2. BJ’s Wholesale Club: It costs $60 a year for the Club Card membership. It recently adjusted its fees to stay competitive with the other giants.

3. Costco: The big dog is also the most expensive. A basic Gold Star membership will set you back $65 a year. It doesn’t often do the same kind of deep-discount membership drives you’ll find at Sam’s, so don’t hold your breath for a half-off deal.

If you’re a heavy spender, the upgraded tiers (Executive at Costco, Plus at Sam’s, or Club+ at BJ’s) all offer 2% cash back, but cost roughly twice as much annually.

You’ll usually need to spend about $3,000 to $3,250 a year to break even on the extra membership cost. (Related: “Which Warehouse Membership Actually Pays for Itself — Costco, Sam’s Club or BJ’s?”)

Who wins the grocery wars?

Membership fees are just one part of the equation. What matters more is the price of the stuff in your cart. When it comes to the basics — milk, eggs, flour and coffee — the winner isn’t who you might expect.

While Costco’s Kirkland Signature brand has a massive following for its quality, it isn’t always the cheapest. In head-to-head price checks, Sam’s Club often edges out both competitors on price per ounce for pantry staples.

For example, Mashed found that Sam’s Club often has the lowest prices for two dozen eggs and large bags of flour compared to the other two. (Related: “5 Ways Sam’s Club Is Better Than Costco”)

BJ’s tends to be slightly more expensive than Sam’s Club on a per-unit basis, but it has a trick up its sleeve that the others don’t.

The BJ’s coupon loophole

If you’re the type of person who uses coupons, BJ’s is your best friend. It’s the only warehouse club that accepts manufacturer’s coupons. You can stack those on top of BJ’s own store coupons to drive prices way down. (Related: “6 Things BJ’s Members Can Get for Free”)

Costco and Sam’s Club don’t touch manufacturer’s coupons. They offer instant savings, which are basically just sales, but you can’t bring in a coupon you found to save another dollar on your cereal. If you’re brand-loyal and a coupon pro, BJ’s might be your cheapest option regardless of the shelf price.

Gas, tires and technology

Cheap milk is great, but the real savings often happen at the pump. All three clubs offer discounted gas, and it’s almost always cheaper than the station down the street. However, you’ve got to factor in the cost of wait time.

If you’ve ever tried to get gas at a warehouse club pump on a Saturday morning, you know it’s a test of patience.

Checkout lines can be long too. Here’s where Sam’s Club stands out, after having made a huge push into technology to solve this. Its Scan and Go app makes the checkout process much faster than the old-school lines at Costco. In fact, Sam’s Club recently beat Costco in customer satisfaction surveys because of that tech.

Costco is trying to catch up by testing more mobile features, but for now, it’s still lagging. However, it recently boosted its cash back on gas to 5% for cardholders, which is a major win if you’re a commuter.

The bottom line

If you want the absolute lowest out-of-pocket cost for a membership and the lowest everyday prices on staples, Sam’s Club is the winner. It’s the Walmart of warehouse clubs, which makes sense since Walmart owns it.

If you’re a coupon fanatic who wants a grocery-store-like experience with bulk prices, BJ’s is the move.

And with Costco, you’re paying for quality and a better return policy. It’s rarely the cheapest in a race to the bottom, but many fans find the Kirkland Signature brand quality is worth the extra few bucks. Just make sure you’re actually using the membership enough to justify that $65 cover charge.
