Cashback causes price hikes on Ebay

MSN has been using incentives to use their live search engine. This is the reason they are giving Cashback(which is a kind of mail in rebate but online) to people who search and click on Cashback links. Some retailers you can get 30% off from. In particular Ebay which sellers have been using CashBack as a way to hike up prices. Basically increasing the price so that they get a higher amount. While telling you the buyer to use Cashback to get back the other money back. While you do get a decent deal you do have to wait 60-90 days to get this Cashback rebate. Honestly I am not liking this trend and can't wait til MSN stop with these Cashback offers.
