Priceonomics is the price guide for everything. We’re based in San Francisco, CA.

Price guides are helpful for buying and selling used things. How much should I spend on this used phone on eBay? What’s a good price to list my stereo system for? Is this used Vespa a good deal, or what?

We hate getting ripped off or over-paying for stuff so we built Priceonomics. We search and analyze hundreds of millions of listings on the web to build our price guides. We hope you can use these reports to get the most value for the best price.

Today, we provide price estimates for used bicycles, televisions, speakers, monitors, turntables, computers, cell phones and much more. Some day soon, we’ll cover just about anything you might want to buy or sell. We’re just getting started.
