No purchase necessary on Pepsi / iTunes Music Store Promo
From the Official Rules page at Apple:
To receive one free game piece and a copy of Official Rules, while supplies last, send a self-addressed, stamped envelope postmarked on or before 3/31/04 to: Pepsi iTunes Game Piece, P.O. Box 9205, Young America, MN 55558-9205. Residents of the state of VT may omit return postage. Limit one free game piece per request per stamped outer envelope. Pepsi-Cola Company (“Sponsor”) assumes no liability for lost, late, stolen, illegible, misdirected, mutilated, incomplete or postage-due mail or requests.
If any of you want a chance to win, but find Pepsi itself reprehensible, this is another option. For me, Diet Pepsi just became my new water.
