Jason has been using Card Dealer Pro since 2024! When he started, he had just 8,000 listings on eBay. Today, thanks to Card Dealer Pro, he’s grown to over 23,000 listings—and counting. Now, with our new inventory management feature, he’s able to seamlessly list on both the CollX App and eBay.

"The inventory management allows me to list my cards to several different platforms while also managing to delist the cards from all platforms when it eventually sells. Because of card dealer pro I was able to expand to multiple other platforms outside of eBay like the CollX marketplace where I have found tremendous success.”
Jason has some tips for Finding Untapped card markets.
1. Scout emerging players Use MLB Pipeline or Prospect Live to track hot prospects and watch their pricing trends on eBay or CollX.
2. Explore niche sets Search for less-common releases like Japanese Topps, Panini Stars & Stripes, or Leaf Draft to find undervalued cards.
3. Check rarity data Use /# searches (eg “/99”along with player name) to find low serial numbered cards on CollX and eBay, which are always in higher demand.
