Every time I ring up a total of $2500, I get a gift certificate. Now I'm not advocating a credit card spending craze by any means, but I use my credit card for almost everything, so I ring up $2500 pretty quick.

It's nice to get a little back. I picked up a Linksys Wireless USB adapter tonight for $20. It was $49.99 at Amazon, I had a $25 gift cert, and I used one of
these codes. Final cost, $20 shipped.
