Amazon: Spend $20 on Magazine subscriptions, Get a $10 credit

Order at least $20 worth of magazine subscriptions at Amazon.com in the month of February, and get a $10 credit on or around March 4th (this credit can be used on ANYTHING at Amazon.com!).  Amazon makes it easy because they even have a bunch of magazines that are "2 for $20".  A lot of subscriptions off Amazon are pretty cheap anyways.  However, most of them are "auto-renew" - but you can go into your Amazon account easily and change this after the fact.
