The sweepstakes, which kicks off on May 1 and runs through August 31, 2010 is being held in conjunction with up to 40,000 of XYIENCE?s independent retailers across the United States (excluding Ark., Fla., Miss, N.C., N.Y., R.I. and S.C.)

Winners will be selected at random and announced in mid September.

XYIENCE will also award 10 second-place prize packages that will include a video game console and a 2010 edition of an MMA video game. Thirty third-place winners receive gift cards redeemable for a future UFC pay-per-view event.
