If you’re looking to save on groceries, gas, and everyday items, warehouse clubs like Costco and Sam’s Club promise big value. But is one actually cheaper than the other?
Both stores offer bulk discounts, store-brand deals, and exclusive member perks. But when it comes to prices, there are a few key differences to know before you commit.
Membership Cost and Perks
Before you shop, you have to pay for access. Both stores charge an annual membership fee.
- Costco: Basic membership is $60 per year. Executive membership is $120 and offers 2% cashback.
- Sam’s Club: Basic membership is $50 per year. Plus membership is $110 and includes 2% cashback, free shipping, and early shopping hours.
Sam’s Club is slightly cheaper to join. But if you spend a lot each year, Costco’s executive rewards might make up the difference.
Grocery Prices
When it comes to everyday groceries, Sam’s Club often wins on price—especially on packaged goods and snack foods. Sam’s frequently runs instant savings and digital coupons that apply automatically.
Costco, on the other hand, offers higher-end and often organic options. You’ll see better-quality meat, seafood, and bakery items, but the prices might be a bit higher.
If you’re shopping for large families or basic snacks in bulk, Sam’s Club may give you the lower bill. If you want organic or premium products, Costco might give you better value for what you’re buying.
Store Brands: Kirkland vs. Member’s Mark
Both stores rely heavily on their in-house brands to offer low prices without cutting quality.
- Kirkland Signature (Costco): Widely praised for quality, especially on items like toilet paper, olive oil, batteries, and bacon.
- Member’s Mark (Sam’s Club): Consistently low-priced and solid quality, though reviews vary more by product.
Overall, Kirkland often outperforms on quality, but Member’s Mark sometimes beats it on price. Your decision might come down to which specific items matter most to you.
Gas Prices
Both Costco and Sam’s Club offer discounted gas at locations with fuel stations. On average, gas at both clubs is about 5 to 25 cents cheaper per gallon than regular gas stations.
Prices are often very similar, but some regions report slightly cheaper fuel at Sam’s Club.
One small note: Costco often requires an executive membership to access certain gas stations during peak hours, while Sam’s Club may offer more open access depending on location.

Electronics and Big-Ticket Items
Both retailers sell TVs, laptops, and major appliances at warehouse pricing. Sam’s Club might offer lower sticker prices, especially during seasonal sales.
Costco tends to win on warranty and return policy. It offers extended warranties on many electronics, plus a 90-day return window for major tech items.
If you care most about price, check Sam’s Club first. If you value support and peace of mind, Costco may be the smarter buy.
Pharmacy and Optical
Both stores have pharmacies and optical centers with member pricing.
- Costco Pharmacy: Offers low cash prices and doesn’t require a membership in some states.
- Sam’s Club Pharmacy: Offers a prescription savings program for Plus members with deep discounts on generics.
Sam’s Club may save you more if you’re a Plus member. Costco holds an edge if you’re not upgrading your membership and want reliable access to discount prescriptions.
Return Policies
Costco is known for one of the best return policies in retail. Most items can be returned anytime, with or without a receipt. Electronics have a 90-day window.
Sam’s Club allows returns for most items, but some categories like electronics and certain large items have a 30-day limit. Their policy is still generous—but Costco’s flexibility is hard to beat.
If you’re unsure about an item or change your mind often, Costco gives you more breathing room.
Online Shopping and Shipping
Sam’s Club offers free shipping for Plus members and often features more items available online than in-store.
Costco has a growing online store, but many items include a shipping fee unless marked otherwise. It also partners with Instacart for same-day delivery, but this can raise prices.
For frequent online orders, Sam’s Club may be more convenient and cost-effective.
Final Verdict
So, who has better pricing—Costco or Sam’s Club?
- Best for budget shoppers: Sam’s Club
- Best for higher quality: Costco
- Best for online deals: Sam’s Club
- Best for returns and warranty: Costco
- Best gas prices: Tie (depends on location)
- Best membership value at the basic level: Sam’s Club
- Best premium membership perks: Costco, if you use the cashback
Ultimately, the best choice depends on your priorities. Want rock-bottom prices and strong online deals? Sam’s Club has the edge. Want higher-quality items and a generous return policy? Costco might be worth the extra fee.
If you’re lucky enough to live near both, test each with a one-year membership and track where you save more. You might be surprised.
