Jimmy's Pokemon Deal Finder - Find eBay deals on Pokemon cards and other collectibles

This site automatically finds underpriced Pokémon cards and other collectibles on eBay by comparing live listing prices against historical market values. It scans tens of thousands of listings every day across the US, UK, Germany, Canada, and Australia to surface genuine deals you’d otherwise miss. Filter results by auction or Buy It Now, ending soon, region, and custom search terms to zero in on the most relevant deals for you.

I’ve been working on this for about a year and a half. It originally started as a command-line script I built for myself that scraped eBay and PriceCharting to find underpriced Pokémon cards, dumping the results into a .txt file for me to review manually. Over time, I decided to turn it into a website and have been iterating on it ever since. One of the biggest challenges has been accurately identifying legitimate deals. Early on, there were a lot of fake or misidentified cards slipping through. I’ve gradually improved the matching logic, but the biggest improvement came from adding the ability to manually exclude listings and ban sellers. That made it possible to filter out sellers consistently listing fakes or mislabelled cards, which significantly improved result quality. I'd love to hear what you all think of the site.
