I've added [Stamped] versions for all of these now.

All of these error sales should be removed when we see them now.  Please give me a link to a card that has some of these sales and I will remove them.  Thank you

If there are "Holo" and "Non Holo" versions or "Stamped" or "Prerelease" versions we want to do know about those.  Please send us an email with the card that is missing.  Something like "Snorlax [Stamped] #123" then we can work to add it to the site so the prices are kept separately for the different version.  It is very difficult for us to go through a series of images to find the versions that are missing.

This is already possible.  There is a "notes" section on every page.  Click "item details" or scroll to that section to find it and make changes or read what people have added.

There is a description field too for people to describe the game and the overall game play and story etc.

You should be able to click the headers and the data will be sorted by the other grades.

Yes, please do add any homebrew titles to the site.  Please add [Homebrew] to the end of the title so people know what it is and add a release date so people can filter out unlicensed stuff released after the console was discontinued.  Some people only want complete collections of licensed games.

I'm going to close this request though because people can add these to the site.
