Most of the time, we'll be able to automatically charge the credit card you've inputted before bidding. However, there is the odd chance your bank blocks the transaction, or your card information is not correct.
No worries! To pay for your item(s), head back to the auction and go into My Cart (found on the left on Desktop or in the menu on Mobile devices.)
If you're not already logged in, you'll want to do so with the exact same email you used for bidding.
Afterwards, you'll be able to see which item's you've won and complete the payment process!
