Help, Your collection
Editing and removing copies
To change a copy, switch to the list view on your collection page. Each copy has its own buttons for Photos, Edit, and Remove.
Edit lets you change the condition, what's included, your notes and prices. Remove takes the copy off your shelf. This doesn't affect the game in the catalogue, only your own collection.
If you own several copies of the same edition, each one shows up as its own entry, so you can keep track of them separately (i.e. a sealed copy and a loose cartridge).
