I'm trying to place an order on Joann's website using a Discover Card and a gift card. At checkout it takes all the info and gives me a total but when I hit the last "Continue" button it keeps tellling me to enter a valid credit card number. It's the same credit card I've been using since 1988, there's no balance due on it, and I've used it on the website and in the store. Does anyone know what I'm doing wrong? (I order a lot on-line so I'm not a rookie-just never had this happen before.) Of course Customer Service is closed today.
Thanks for your help!
