Flippity is a Google Maps mashup of eBay listings. The site allows users to search eBay listing by object and location and view the results on a Google Map.
The photographs of the results are displayed beside the map. You are also able to refine your search by price and by distance. Another really nice feature is that when the results of a search are returned Flippity automatically loads subcategories for your search term in a drop down menu, allowing you to refine your search further.
