Well, I never used these before and my bro just got one and posed an interesting question that I hope you guys can help me with.

My bro got a prepaid MC so he can buy shit off the Playstation store. He bought Mortal Kombat 2 but when he did, he got a message saying if his card is inactive for six months, they will charge him $2.50.

His question to me was is there any way to prevent this from happening? My thought was maybe to just use up all the money on the card then it becomes unusable but I don't really know. Any thoughts? Thanks.
