Forgive me if someone already posted about this, but I just found out about this. It looks like you follow their portal into amazon.com, give them your bitcoin address, and they send you a small percentage of the purchase price back to you in btc. Looks pretty cool, I'm going to try it next time I buy something on amazon. If anyone else tries it, let us know how it works out.

oh I didn't know someone was already doing that. Well, you're right, nothing wrong with competition.
