Costco vs. Sam's Club vs. BJ's: Is the Membership Worth It in 2026?

Warehouse club memberships work when you actually use them. They don’t when you don’t. The math is straightforward, but the right club for you depends on what you buy, what’s near you, and a couple of structural differences that aren’t obvious from the outside.

Here’s the side-by-side in 2026, with the honest verdicts.

The membership tiers

Costco

• Gold Star: $65/year
• Executive: $130/year (includes 2% cashback on Costco purchases, capped at $1,250/year)

Sam’s Club

• Club: $50/year
• Plus: $110/year (includes 2% cashback on Sam’s Club purchases, capped at $500/year; free shipping)

BJ’s Wholesale Club

• Club: $60/year
• Club+: $120/year (includes 2% cashback, free shipping)

The break-even math

The 2% Executive/Plus/Club+ tiers pay back the upgrade cost at:

• Costco Executive: $3,250 in annual Costco spending (Executive costs $65 more than Gold; 2% of $3,250 = $65). After $3,250 in spending, you’re earning back beyond the membership.
• Sam’s Club Plus: $3,000 in annual Sam’s Club spending.
• BJ’s Club+: $3,000 in annual BJ’s spending.

The baseline membership ($50–65) typically pays back if you save 5% on $1,000–1,300 in annual purchases versus shopping elsewhere. For most households that genuinely use the club for groceries, fuel, prescriptions, or one-off appliances, this break-even is reached easily.

What each club is best at

Costco wins on:

• Quality across the board. Kirkland Signature private label is consistently in the top tier of comparable products. The reputation is earned.
• Gas. Costco gas is typically $0.20–0.40/gallon below local stations. Costco gas alone pays the membership for households driving 12,000+ miles/year.
• Optical and hearing. Costco optical is one of the cheapest places in the country for glasses and hearing aids. Frames + lenses for $150–200 vs $500+ elsewhere.
• Prescription pharmacy. Often the cheapest pharmacy for cash-pay or high-deductible prescriptions, including for non-members in some states.
• Travel. Costco Travel is genuinely one of the better rental car booking tools on the internet. Cruises, hotels, vacation packages.
• Return policy. “If you’re not satisfied, return it” is unmatched by competitors. Includes electronics.
• Appliances and electronics. Free 2-year extended warranty on TVs and computers via Concierge service.
• Specific items that are nearly always the cheapest: rotisserie chicken ($4.99 unchanged since the 1980s), Kirkland Signature dish soap, Kirkland clothing basics, Kirkland nuts and dried fruit, large-format meat, organic produce, baked goods.

Sam’s Club wins on:

• Fuel. Sam’s Club fuel is often a few cents cheaper than Costco in markets where both compete.
• Scan & Go app. Skip the checkout line entirely by scanning items in the store. Best-in-class in-store experience.
• Single-membership card for households with two shoppers. Sam’s Plus and Costco Executive both allow two cards per membership.
• Free curbside pickup with Plus membership.
• Walmart-style integration. Sam’s Club deals occasionally sync with Walmart promotions in interesting ways.
• Slightly cheaper baseline membership.

BJ’s wins on:

• Manufacturer coupon acceptance. BJ’s accepts traditional newspaper-style manufacturer coupons. Costco and Sam’s largely don’t. For couponers, this is a structural advantage.
• Smaller pack sizes. BJ’s pack sizes are often smaller than Costco/Sam’s, which is better for smaller households that don’t want 96 paper towel rolls.
• East Coast presence. Dense in the Northeast and mid-Atlantic where Costco/Sam’s are sparser.
• BJ’s Easy Renewal. Auto-renewing membership includes some perks.
• Lower-priced gasoline in some markets.

What none of them are great at

• Pure household basics where the unit-cost wars are already won. Aldi, Walmart, and Trader Joe’s often beat all three on staples like milk, eggs, and bananas.
• Specialty items. A Costco-sized container of an item you’d use once or twice isn’t a deal.
• Apartment-sized households. Storage matters. A pallet of toilet paper requires somewhere to put a pallet of toilet paper.

The pharmacy hack (especially Costco)

If you take regular prescriptions and your insurance has a high deductible, Costco pharmacy often beats your insurance copay. Federal law requires pharmacies to fill prescriptions for non-members in most states, so you can use Costco pharmacy without a membership card in many places. If you’re already a member, you can compare cash-pay vs. insurance for every prescription — the cheaper one wins.

GoodRx coupons stack at Costco for additional savings.

The travel hack (Costco Travel)

Costco Travel runs at lower margins than typical OTA platforms. Rental cars, cruises, vacation packages, and Disney bookings are often 15–25% below Expedia for the same itinerary. The trade-off: limited modification flexibility, less convenient booking interface, fewer partner brands.

For rental cars specifically, Costco Travel doesn’t charge until pickup, lets you rebook freely if prices drop, and includes the second driver fee. This is one of the best rental car tools available.

The verdict

For most households: Costco Gold Star ($65) is the right starting point if there’s a Costco within reasonable distance. The break-even is easy, the quality is reliably high, and the ancillary services (pharmacy, optical, gas, travel) are real value.

Upgrade to Executive ($130) if you spend more than $3,250/year at Costco. For families with 2+ kids, this happens almost automatically.

Sam’s Club ($50) is a solid alternative for households closer to a Sam’s, especially if Scan & Go appeals to you (it’s genuinely better than Costco’s checkout experience).

BJ’s ($60) is the right pick on the East Coast, especially for couponers and smaller households.

Multiple memberships rarely make sense. Unless you’re running a small business that buys for resale or has very specific needs, pick one and use it well.

The trial trick

Costco, Sam’s Club, and BJ’s all offer paid trial periods or money-back guarantees on membership. If you’re not sure, sign up for one year, track what you spend, and decide on renewal whether the math worked. Costco’s “100% guarantee on membership” means you can cancel any time during the year and get a prorated refund.

That’s the entire warehouse club calculus. Pick the right club for your household, use the ancillary services, and you’re net-positive within the first quarter.
