At what point do you find out if a guest has given you a "bad" credit card number? If I enter their information into P3, and submit the order with my Pampered Chef credit card info, HO sees that I paid for the entire order with a good caredit card, and they will pick and deliver the items, as they should. But where in the process would I be informed that a credit card from a guest is a bad card? Obviously, I can tell if someone has passed a bad check when my bank notifies me [and BEFORE I submit the show], but I'm confused on the credit card issue. Sorry for a dumb question, but I just had two shows this weekend where guests gave me their credit card info, and because I do not know these people, I'm a little concerned.
