Warehouse club math used to be simple. Pay a yearly fee, drive to a big building, save money in bulk.
Online changed that. Now there are delivery fees, upgrade tiers, curbside pickup, same day options, and item prices that are not always the same as what is on the shelf inside the store. So we bought both memberships, kept them active for two months, and priced twenty two identical or near identical items on each site.
Here is what the math actually looked like.
Quick Comparison
| What We Checked | Costco | Sam’s Club |
| Base membership | Higher annual fee | Lower annual fee |
| Upgrade tier benefit | Annual 2 percent reward | Annual reward plus free shipping |
| Free shipping on base tier | Limited to some items | Limited to some items |
| Curbside pickup | Not offered at most locations | Widely available |
| Scan and go in store | No | Yes |
| Cheaper on our 22 item basket | 13 of 22 items | 9 of 22 items |
The Membership Fee Question
| Membership Element | Costco | Sam’s Club |
| Base tier annual fee | Higher | Lower |
| Upgrade tier annual fee | Higher | Lower |
| Free shipping on base tier | Limited items only | Limited items only |
| Free shipping on upgrade tier | Not included | Included on most eligible items |
| Annual cash reward on upgrade | Larger percentage | Smaller percentage |
| Reward cap | Applies | Applies |
| Household cards included | Yes | Yes |
| Curbside pickup on any tier | Not at most locations | Widely available |
Winner: Sam’s Club for online heavy shoppers. Costco for in store heavy shoppers.
Pricing Across 22 Items
We priced pantry staples, paper goods, a rotisserie style chicken, coffee, olive oil, laundry detergent, batteries, dog food, a bag of frozen fruit, and a few household basics.
Costco came in cheaper on thirteen. Sam’s Club on nine.
The gaps were mostly small. On sixteen of the twenty two items the difference was under four percent, which is inside the range that a single promotion could flip in either direction any given week.
Where Costco pulled clearly ahead was on its own house brand across food categories. Where Sam’s Club pulled ahead was on brand name paper goods and a couple of household cleaning items.
Winner: Costco. By a small margin, driven mainly by house brand pricing.
Delivery and Pickup
Sam’s Club has curbside pickup at almost every location we checked. Order in the app, park in a numbered spot, someone loads it. We used it four times and never waited more than seven minutes.
Costco does not offer curbside at most warehouses. You either shop inside or you pay for delivery. That is a real inconvenience for anyone with a car seat in the back and no interest in walking a warehouse floor.
Costco does partner with a same day grocery delivery service, which works, but prices on that platform run higher than in warehouse prices on a lot of items. We compared six and found markups on all six.
Winner: Sam’s Club. Curbside alone decides it.
The App Experience
Sam’s Club has Scan and Go, which lets you scan items with your phone as you shop and skip the checkout line entirely. We used it and it works exactly as advertised. Walking past a twenty person line is a genuine feeling.
Costco has no equivalent. You wait in line like everyone else, and then you show your receipt at the door.
On the website side, both are functional and neither is fast. Costco’s search is the weaker of the two in our experience, often returning loosely related items above the exact thing you typed in.
Winner: Sam’s Club.
Return Handling in Costco vs Sam’s Club
Both clubs have generous return policies and neither gave us any trouble.
We returned an opened bag of coffee to Costco with no receipt and got a refund in about four minutes. We returned a small appliance to Sam’s Club and it took about the same.
Electronics carry a shorter window at both. Check that specifically before buying a television or a laptop from either.
Winner: Tie.
Product Selection
Costco’s food selection was stronger in our comparison, particularly on prepared foods, cheese, and bakery items. The house brand covers more categories and covers them well.
Sam’s Club had a broader spread of national brand names in household and cleaning categories, which matters if you are loyal to specific brands and do not want a house label substitute.
Neither club stocks everything. Both rotate inventory, which means the item you loved last month may simply be gone.
Winner: Costco on food. Sam’s Club on branded household goods.
Choose Costco If
- You buy a lot of food and are happy with house brand quality.
- You shop in person more than you order online.
- You want the stronger prepared food and bakery selection.
- The higher annual reward percentage suits your spending level.
Choose Sam’s Club If
- You order online regularly and want shipping included.
- Curbside pickup would change how often you actually go.
- Skipping the checkout line matters to you.
- You want a lower base fee to test the format first.
Final Verdict
The old answer was Costco, and on pure grocery pricing that answer still holds up in our basket test.
But the question in this article was about the online experience, and there Sam’s Club is the more modern operation. Curbside at nearly every location, Scan and Go in the app, and a shipping benefit built into the upgrade tier. Those are three things Costco does not currently match.
If you are choosing one and you buy most of your food from a club store, Costco is still the safer pick. If you want the club to fit around a schedule that does not include a weekend warehouse trip, Sam’s Club is the one that adapted.
We will revisit this if either club changes its fee structure or shipping terms.
