http://www.mallagent.com offers comparison shopping for almost all
consumer product categories. The site is especially good for people
knowing exactly what they want to buy and try to find the best price.
It actually simulates user’s browser to send out multiple concurrent
agents with a single click from the user. The result is a ‘pile up’ of
filtered search result from each site in one page.
