Amazon 10% Coupon Code
Today (12/9/12), in email I received a message from Amazon with a 10% off coupon code valid on a purchase of $300 or more! My husband got the same email for a purchase of $200 or more. Not sure why it would vary, I spend much more on little things than he does.
The email is sent from Amazon.com <email@example.com> and is titled 10% Off Your Next Purchase of $X00 or More.
