If the card is a "Personalized" card with your name on it, then there is a $3 monthly fee. Cash reload fee is $3; however direct deposit is free. $1 per month if you want a paper statement. If you just got the temporary card then you should call to make sure that the account is closed as they charge a $2 inactivity fee after 13 months of no usage. Not sure how they track that (identifying that you own the card) unless they only impose the fee if there is money left on the account.

I understand that you only purchased this for online gaming but isn't this sad that some people who can't get bank accounts go with cards like this? Yikes.
