If my credit card gets denied one more time as a result of "unusual activity" I'm going to scream. It's getting very, very aggravating. It used to just be when I would travel out of state. Now it's when I charge more than a certain amount in one day. I'm sorry. Sometimes my Saturdays are busy and I spend more money than usual - is that a crime? People do make large purchases on credit cards for the rewards points you know!

How about a code that says - check signature and ID carefully - instead of flat out denying the purchase and leaving the cardholder stammering about how there's nothing wrong with the card, and that yes, I suppose I do want to apply for Target card and save 10%, since that's the only way I'm going to leave the store with the stuff I want to buy?
