We have been hearing about local search over the past year or two. The search engines like Google, Yahoo, Ask Jeeves and even MSN have been promising and providing enhanced local search options. The next revolution in local is by a new shopping search engine named StepUp.com. You enter in a zip code and then conduct a search on the product you are looking for. It takes a few seconds and then products start coming up. Not only does this site provide detailed information on the products (provided by the merchant) but it also shows you the closest places with driving directions to the store. In addition, they have fields such as "Quantity On Hand", "Product Listed", and "Product Updated" to help with your purchase decision.
