I just placed an order, but my card was charged more than once.

You are probably experiencing multiple authorizations, which occurs after a card has been entered multiple times, even if there were not multiple purchases. While one charge is processing, the other charge was declined. These charges will be dropped within 1 to 3 business days, and only one charge will settle (all other charges will remain in your account as pending charges until they drop). If two or more transactions were to settle, please contact us so that we can better assist you.
