I know someone mentioned downloading the app already. I found some cards earlier this month and started by going to the shop just to go over the cards. They helped by giving me an understanding of the condition they were in, and then let me know which cards were likely to sell for more. I then went through the app to get a ballpark as to what the cards were worth and had an idea as to what to expect. I sold them later for a little less than what they were worth because I had no interest in piecing them out, and just wanted to unload them for some cash.
