This site finds the best deals on eBay cards and other collectibles on eBay by comparing listing prices to historical valuations. Scans thousands of deals daily and shows the best deals sorted by bigger price difference percentage.

The site supports Pokemon, LEGO, One Piece, YuGiOh, Dragonball, Lorcana, and Funko POPs. It allows you to search by keywords, region (US, UK, Canada, Australia, Germany), seller country, auction type (buy it now, auction), and also lets you search by auctions ending soonest to catch last-minute deals.

The main benefit of the site is that it only shows deals that are under market value, so every card is undervalued compared to market, with many deals being significantly under market.

This originally started as a personal project to find deals on Pokemon cards for myself. It was a CLI script that would scrape eBay and Pricecharting and write the best deals to a .txt file for me to review.

I've been running the site for a year and a half and have had generally good feedback from users.

When I first launched the site, the biggest problem was fake or mislabelled cards. Most of the top deals on the site were listings like "Mew #150 acrylic art case", "Mewtwo #260 handrawn card", "Charizard #4 phone case". There were also proxy cards and bootleg cards as well as cards that had been labelled as a different card.

I added a lot of filters to the listings scraper to filter out a lot of these cards, but the biggest improement to the listings quality came when I added the option for me to manually exclude listings and ban sellers. Once I banned a handful of the bad sellers, the listings quality improved significantly. Now almost al of the deals on the site are legitimate and labelled correctly, with a few bad listings slipping through here and there.

Another big improvement to the quality of the lsitings came from identifying graded cards properly. A lot of sellers would put "PSA 10" in the title for a card that was ungraded just to attract attention. I wrote a script that uses OCR to detect a PSA label and the words "MINT" or "GEM MT" in the listing image to make sure the image was genuinely a graded card. Since adding this, the graded cards on the site have been 100% accurate with no false positives from the OCR script.

The site has been growing steadily and people seem to find it useful so I'm very happy with how the site is doing. Please let me know what you think if you check it out.
