  • So many bugs/ glitches

    By Alex90990
    Great concept terrible execution. Frustrating when trying to set filters that don’t work to find cards you want. Going through 5000 gleybar Torres cards because you are only able to skip one page at a time is quite an experience.
  • Increase bid not working

    I am not able to increase my bid on cards that I have already bid on
  • The best sports card app on the internet

    By BradJohnson25
    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.

  • 5 out of 5

    By General__VonBeck
    If I could give this app/site 6 out of 5 stars, I would. Selling cards is daunting and this company takes the effort out of it for the user.
  • Best app ever

    By Jinksm
    5 star app
  • Great App Overall

    By Brady Smo
    Wish it had prices and comps on raw cards too, not just graded slabs.
  • Unable to verify user; worthless app

    By Barcle101
    You cant log-in. Verification process is miserable and unsuccessful. UI is horrible. Not sure why anyone bothers to use them
