If you use the Amazon’s new A9 search engine (which is actually a pretty slick system), you’ll get approximately 1.5% off your Amazon purchase. Sounds like a pretty good deal to me, and a great incentive for people to use the search engine.
On a side note, if you want to send a few pennies my way, you can search for Amazon goods using the form on this site (down in the right column). I think I’ve gotten a total about $.43 (yes, there is a decimal-point there) from it, but I figured I’d plug it anyway.
