I love Amazon, and I love online shopping... So when I saw Discover Card offering the following I was quite happy:
Sign up for 5% Cashback Bonus on up to $1,500 in purchases at Department Stores and for all Online Shopping from October 1 through December 31, 2012.
But then I found out I could refer people and we both get $50 bonuses? Awesome!
Oh, and by the way, you can spend your cashback directly on amazon. But don't forget to grab Amazing Affiliate Link v1.0.1 for Google Chrome if you haven't already :-)
