Debit cards often have transaction fees associated with them that the customer pays (as opposed to the merchant paying). Even when they don't, running it as debit doesn't get you cash back or rewards or various things that running a card as credit gets you.

You always want to run your American debit card as a credit card if the merchant allows.
