AuctionShark has launched an online-auction search service that lets shoppers search once and review auctions from eBay, Amazon, Yahoo and Overstock Auctions. Buyers can enter their search at AuctionShark and see live results from multiple sites in one place. The site currently returns listings from eBay, Amazon, Yahoo and Overstock Auctions.

Additional features include watch and wish lists that allow users to save and share items from multiple shopping sites in one common location. Users can save and set their searches to run automatically so that they receive email notifications anytime a new match is found, and there's an option to receive item ending reminders via email or cell phone.

Michael Zak, a principal of AuctionShark, said they will be adding new auction sites within the next week and will continue to evaluate and add auction and shopping sites to the multi-site search.
