A:AnswerYes! As long you redeem the code the funds will be added to your wallet. when checking out make sure you select to pay with the wallet since it's not the primary payment method by default (default will be your credit/debit card) . i've done this many times for fifa points.
A:AnswerYou can't get more than 1 of these - that is the limit. You can do the 25$ and the 15$ together at checkout but no more than only 1. It's supposed to be 1 day for the reset but it might still cancel because of system delays.
