There are a few reasons we may reject your card (sorry!). The most common is that the balance you stated does not match what is actually on the gift card or the card number/pin was entered incorrectly, making it invalid. Not to worry! You can always list the card again with the corrected information.
Another common reason is that our external verification software declined the transaction. Unfortunately, we don't know all of the reasons for the decline, but we work very closely and trust this system. It helps protect us and our customers!
