Price Advance Launches to the Public
Chicagoan Roddy Richards (StartupSchwag) and New Yorker Adam Gotterer (CollegeHumor) have just recently launched the PriceAdvance browser plugin to the public.
The plugin shows you what the product that you’re after costs at other merchants across the web as you shop.
For example, surf to BestBuy.com and look at a flat screen TV and PriceAdvance will show you what that same TV costs at Buy.com, Amazon and others. If you see a lower price, just click on it and you’ll be taken directly to the product page on that store’s site.
Right now PriceAdvance supports 19 online merchants (with more in the works) and is compatible with Internet Explorer and Firefox.
Since it launched in beta this December the plugin has saved its users over $100,000. I’d imagine the major impediment to a rapid increase in stores supported by the plugin is the quality of some merchant sites and the availability of their data. Check out the demo below:
