When setting up billing for your Tictail shop, you may see a $1 charge on your card (or the equivalent amount in Euro or Swedish kronor).
This is not a real charge and no money has been drawn from your account. It is simply a reservation—of the smallest amount possible—our payment processing system uses to verify that the card is working correctly. The charge should disappear from your bank statement in a few days.
This is a standard industry practice to validate credit cards online and we promise it's nothing to worry about :)
