I am not sure if those of you who used to deposit via all access pre paid cards (which no longer work) but PokerStars dad (deposit help) has recommended Vanilla Mastercard as a deposit option to their site.
As of five minutes ago, i can CONFIRM this works. I bought the Vanilla Mastercard (it says "easy bill pay" on it with a big green $ sign on it) at Walgreens, and it cost 5 bucks to load money onto it. I logged on to PokerStars, deposited and played.
Not sure if this has been reported here, but i wanted to help my fellow U.S. players who have had problems deposting since the All Access cards stopped working.
