MHO: Costco is a little more "upscale."
The products are a little higher-end, but about the same price.
Both take ATM/debit cards. As for credit, Costco takes AMEX only, Sam's takes DISCOVER only (oh, and the Wal-Mart MC, I think).
Around my area (Houston), there are only two Costcos, while Sam's is everywhere.
Costco did have a superior warranty (10 years on virtually everything), but Sam's has now decided to do the same.
