If you click the "Account" tab at the top right of our site, a little way down on that page under the heading Affiliate Credits, there is a line saying "You have $XX.xx available to redeem." That dollar value is how much credit your DriveThruRPG.com account has currently.
For more detailed information, you can also visit the "Affiliate Reports" tool page.
When you check out with an order on our store, there will be an option just above the credit card form that says "Check to use account credit ($XX.xx)."
Simply check the box there, and your account credit will be used toward that purchase. If your account credit completely covers the purchase amount, you don't even have to enter any credit card information. Otherwise, your credit card will be used to pay the difference.
From the "Account" tab on our front page, under Affiliate Credits, click on the "Redeem credits for cash" link. Simply follow the instructions from there. You will be paid via a PayPal payment, so it will make the process go faster if you already have a PayPal account set up.
Note: You will be charged a $2 processing fee to redeem account credit. If you redeem $14.20, for example, you will actually receive $12.20. There will be no other fees imposed by us or by PayPal.
