BOX 4900, Fenton, MO 63099 (“Mail-In Request”). Requests must be postmarked by December 21, 2011 and received by December 28, 2011. Limit one (1) request per outer-postmarked envelope. Upon receipt of your request, a Sponsor representative will “participate” for you in the specified Qualifying Merchant Gift Pool and you will be sent an email which will advise you of the Gift that you are eligible to receive and how to claim it Free Participation requests mechanically reproduced or made in any fashion other than as specified herein are void. Any requests received from a Cardmember who has not registered his/her Card by the time the Free Participation request is received will be deemed null and void. If a request does not include the name of a Qualifying Merchant but is otherwise complete, Sponsor will randomly select a Qualifying Merchant Gift Pool into which request will be entered."
