American Express really wants you to use your AmEx for shopping this season! They have thought up another creative promotion called the Gift Chain where if you register your AmEx first, then every time you spend $25 or more at a participating online store between November 28 and December 21, 2011, you’ll be eligible for a surprise gift worth between $2 and $500 each time (up to 10 gifts max). Thanks to reader Michelle for the tip. Update: Another reader tip is to buy gift cards of $25 from a participating store such as Walmart.com, and repeat as needed. Make sure you can use the gift cards at some point later, perhaps for a single larger item.
Here are the eligible retailers:
