I know that Costco accepts its own credit card or AmEx. Any other credit card? But when I was about to sign up several years ago, Costco told me I had to sign up for the Costco AmEx card which gave a rebate, but no miles.

Does anyone know, can I get miles at Costco using a regular AmEx credit card? Costco also takes debit cards. Are there any debit cards that give miles? I use mainly United and Northwest.
