Citi is giving you a chance to win one of thousands of prepaid cards worth up to $10,000 just for shopping for the holidays! As a Citi customer you can register your Citi credit card or debit card for the Citi Holiday Sweepstakes at stories.citi.com. Every time you use your registered card for eligible purchases from November 15, 2010 through December 31, 2010, you get a chance to win a prepaid card ranging in value from $10 to $10,000. Also, starting on November 19, the Citi Facebook page will support Toys for Tots, by encouraging consumers to post a story about a favorite childhood toy they received as a child. For each story posted, Citi will donate $10 to Toys for Tots, up to $100,000. Citi will also have pop-up events in major shopping areas in New York, Chicago and Los Angeles from November 19 through November 21 to help give back to Toys for Tots, where you can stop by and have your holiday photo taken. For every photo taken, Citi will donate another $10 to Toys for Tots.
