Gamestop Store Credit??

Didnt really know where to post this but...anyways

i recently traded some games in for store credit and they made me sign up for a power up card ...thats all i got from the store lol. im just wondering but is there any way i can check online or anything on how much credit is on the card?? can money even be put on the power up card?? i just wanna make sure the money is still in it, and the gamestop stores are closed today so i cant call or anything...thanks if anyone replies

isn't there a number on the back of the card? i'm pretty sure that it says to check the balance, call this number.. lol

Need to check your Edge Card balance? All you need is the account number and the four digit number on the little scratch off area to check online.
