By default the shopping cart in FoxyCart accepts Discover cards. If your client doesn’t want to accept Discover card credit cards you need to remove it from the checkout. This is a rather simple process.
FoxyCart is a great shopping cart solution for websites. It’s built for designers, making it easy to use. There are some features missing though. One feature is the ability to ship only to the continental 48 states. With a little jQuery code this can be accomplished.
