Zenkau is a comparison shopping site that combines online and local shopping. It allows shoppers to find products they want at the lowest prices across both online and brick-and-mortar retailers. Prices and availability are updated automatically multiple times a day. Here's how it works: 1) Tell Zenkau what you want and your zipcode 2) Zenkau shows you the most relevant products along with the best all-in price (sale + shipping + local tax) available online (e.g. Buy.com, Amazon) AND in-stock nearby (e.g. Target, Best Buy, Sears) 3) If you like an item but dont like the price, then you can add the product to your wishlist and indicate how much you would like to pay. When the price (online or local) drops to that level, you get notified.
