Any bids you placed with the old card are tied to that payment method and cannot be changed mid-auction. But not to worry! If you win the auction and payment declines, you will have the option of fixing the billing error with your new payment method.
In the meantime, please Add your new card information as soon as possible to your account by following the instructions below:
1.) Log In to your PropertyRoom account
2.) On the upper right hand side, hover over your name and select My Profile
3.) Select Payment Info in the left menu
Select Add Credit Card, then fill in the fields as prompted.
* If you want to use your new card for future auctions, be sure to mark it as your default!
