Discover Holiday Mall Promotion

From November 1 to December 31, Discover is offering a $20 Discover Gift Card for every $200 in Discover Card purchases at participating malls:

Just take $200 in Discover Card receipts from any store(s) at a participating mall or shopping center to Customer Service (or the Discover Card Booth) and redeem them for a $20 Discover Gift Card.

Here is the fine print:

Get a $20 Discover Gift Card for every $200 in purchases made with your Discover Card at a participating shopping center between 11/1/2007-12/31/2007, while supplies last. Original receipts must be presented to a participating shopping center's Customer Service Desk (or the Discover Card Booth) by 12/31/07. Limit five Gift Cards per account during the promotion period. See Gift Card terms and conditions for full details.
