Pricepirates is a cool price comparison tool that lets you compare prices for products between different eBay listings and online store offers. It pulls in eBay bid prices and compares them against shopping comparison sites like Shopping.com and Amazon Marketplace.
The software provides ways to find the best offers for what you are searching for, and also includes tracking features and allows you to manage the results.
It even has advanced eBay search options and has a nice tabbed interface that is easy to use and allow for quick switching between results. It is also compatible with all US and international eBay sites.
I used it and discovered that a watch I thought was only available on eBay was also being sold on Amazon – and I didn’t have to pay $15.00 in shipping either.
Wish they’d come out with a Mac client also as I can only use this at work.
