Let me just say whoever made this app did an amazing job. The interface is seamless and easy to use. The app just needs more users create a market within the app to make it worth while to sell and buy. I think a lot of collectors would use the app due to the low fees. It looks to be a fairly new app, as there is only limited cards you are able to sell (mostly basketball). Similar to StockX but solely for sports cards.
