Is it possible that gamestop has Pokemon Black but do they still sell Black?

GameStop may still have copies of Pokémon Black available, but it depends on the individual store's inventory and stock. Due to the release date of Pokémon Black being over 10 years ago, it is not likely to be widely available in most GameStop stores.

However, it is still worth checking with your local GameStop store to see if they have any remaining copies.
