[quote name='PapaSmerf']For game credits, there is usually a check box somewhere during checkout to apply the credit or not.[/QUOTE]
Unfortunately, I'm not finding that. I think its due to the nature of it being a digital purchase, and that it requires me to input my credit card info, rather than loading one that I already have on file. Normally, if I go to "choose another payment method," it takes me to a screen where I can select/deselect credits for my order.
...No such luck this time though.
(Yes, I'm aware that there's not much difference between applying a credit I have now, and using it later, since in the end, the outcome is the same. I was just planning on using the $20 on something else down the line, like another game with a $20 credit.)
