Scouring the net for electronics deals requires a level of research you haven't engaged in since those endless college nights in the library, meticulously studying obscure texts from which to plagiarize. Introducing the nerd who'll do your savings analysis homework for you: Woya.
A newcomer to the price-comparison-site game, Woya sets itself apart by providing detailed price histories on new and used items, giving you the tools to decide whether to buy now or boldly attempt to walk the dirt cheap/obsolete razor's edge. Pulling from major e-tailers (Amazon, Overstock, Google), eBay, and even classified sites like Craigslist and Oodle (all with direct purchase links), there's robust data on 200,000 gadgets like video games, A/V gear, cameras, computers, cell phones, and marine electronics, for any pirates hunting for a barrrrgain. Handy graphs include supply & demand bar charts; pricing matrices comparing retail market price, average classified price, and "fair auction price"; and a line graph w/ new & used/refurbished price points over the previous six months, so you can scope potential savings, or extrapolate an item's future trajectory (note: on its current course a used Wii will one day cost $10,000. Get in now!).
There's also the DealDigger alert program, which'll email you when the object you desire falls within your set parameters regarding seller type and price ceiling, work outsourcing so simple you'll have all the time in the world to rip mad Bloodhound Gang off Napster.
