PokerStars has opened the FPP Store for U.S. players. All previously purchased items have been canceled. Players can only purchase cash rewards with their FPPs based on their VIP tier on April 15, 2011. Players cannot purchase any merchandise with their points. Players are also now allowed to purchase earned but unclaimed Milestone Cash credits as well as unclaimed but earned VIP Stellar Rewards. Any unused points will be held until a time that U.S. players can play again on PokerStars. You can see the U.S. PokerStars FPP FAQ here.
