Gazaro: Your Bargain Hunter
A number of services already search the Web for good deals on your behalf. Gazaro looks like it could be a solid addition by offering not just deals, but an analysis of just how good those deals are.
Gazaro, which is free and open to all, analyzes the price history of a product and tells you whether the price a site is offering is a really good deal or not, based on how prices have been in the past. In other words, $1200 for a particular flat-screen TV may be the best deal you can get now, but it's not a very good deal if the same TV was $1000 a month ago. With that kind of information, you may decide to wait for the price to go down again.
