Good idea with affiliate programs. Here's an Amazon affiliate store I whipped up last night. It's live so feel free to buy something.

When you checkout, it takes you over to amazon.com where you can login if you have an account or create a new one to complete your order.

Most book and DVD purchases can get affiliates anywhere up to a buck or two, depending on the price. Naturally the more expensive something is, the more of a cut affiliates get. I think I snagged about $10 for the cause with the DVD player I just bought to test the system out.
