Using Microsoft's Live Search cashback program, you can get 30% off ebay "buy it now" prices.

My friend who is an ebay fanatic alerted me to it. Basically the terms are that you have to go to and search for something, then click on the link that takes you to ebay. You have a 60 minute session to select your item, it has to be an item with a "buy it now" option, then you have to pay for it with paypal. Create a microsoft cashback account, and within 60 days you get the 30% back into your account.

They've had this program going for a while off and on, it's been at 20%, but now it's at 30.
