I see a lot of talk in this discussion about debit cards. I currently have only a debit card through my bank with my checking account, however, always run it as a visa and NEVER run it as a debit card. A lot of times, for small purchases, I don't have to sign, so it's quicker then running it as debit since I'd have to enter my pin. I don't know why I never run it as debit. Something about entering my pin in line at a store with people around?
