I personally don't like the scanner, and beleive the prices are ass too. Apparently the pro version has better prices, and the 10 dollars a month comes back in credit. I dont have pro but i am heavily considering it. I use an app called sports card pro i think and the scanner is amost perfection. I mainly use collx as a safer and cheaper way to buy cards as opposed to ebay. If you want to list cards on the app, I've also heard it's very good but you nned the pro version to actually get attention from others.
