Woya is super cool new shopping comparison service which lets you compare prices from unusual places like Craigslist, eBay and Overstock as well as the standard Amazon type retailers. The ability to check classified used prices alongside new in the tabbed interface is neat, as is the instant access to multiple product reviews from various sources.

The interface is a tad too cluttered for my liking – the devs could easily remove a few features from the front page and still keep it valuable – but there are definitely some nice touches, like the DealDigger button, which lets you specify a target price for a product and receive an email notification when the system finds it at that price.

Overall it’s a very nice service, and a pretty comprehensive one at that. Lots of community feedback stuff, totally live results and other useful features which all add to the value. Well worth bookmarking if you’re in the US (hint: needs an international version!).
