How in the world does BofA know what portion of your transaction is for cash instruments and what portion is for other stuff?
I agree with Nako. I don't know how, but with my Keybank debit card, I only get the CO miles for a purchase not the cash back. The problem is that I get one mile for every two dollars I spend, and there is an annual fee, so at renewal time, I canceled and will use my credit card if I want the miles.
