Hmm... If you mean money was added to my wallet, that can't be it.  My wallet was at zero last I checked (It was a couple of days before those transactions...)  Also, the money from my grandfathers account is gone (not all of it, just the $98 and change from his total balance.

The money I had spent on my 7 games were already withdrawn from his account.  That was on the 9th of April.  I haven't bought anything after that.
