Best App for Buying and Selling Trading Cards

The functionality of the Alt app is second to none. I’ve had cards in several Vaults and the Alt portfolio tool is by far the best. It gives me real time value of my cards and they make it super easy to view my cards and list in their auctions. I like how the fixed price listings can be pushed to eBay too.

The app allows me to search and create saved searches across 15+ marketplaces - not just the Alt marketplaces. It’s a huge value add because I always forget when auctions are ending. Now I feel like I never miss anything. The instant pricing tool is helpful at card shows too.

The best sports card app on the internet

Alt is hands-down, the best sports card app and marketplace on the Internet. Allows you to easily see recent auction prices aggregated from eBay, heritage, Goldin and others. Also, their liquid auctions consistently carry great selection of both high-end cards as well as more entry level. I also use their vaulting service to store my cards in a safe and insured way.

App Has Great Potential

New user of the app and overall, good experience. Couple of suggestions for enhancements:
1. Great to have dual listings with eBay, but need to support all eBay selling options such as auctions and offers
2. Add support for integrations with other marketplaces than just eBay, such as PWCC, Goldin, etc…
3. Allow Alt users to message others for negotiation purposes and allow both cash and/or trades
4. The UX when searching via the browse capability is awful-the cursor focus jumps around all over the place and the search should support fuzzy matching
5. Increase marketing efforts to make ALT more well know in the industry. Need more users selling via ALT vs. external
6. Improve performance, too slow
7. Every card listed should have an ALT market price value available which should update in near real-time vs. batch jobs which appears to happen daily
