We recent discussed Target's pre-order bonus for New Pokemon Snap, which is a magnetic photo frame. If that's not up your alley, perhaps GameStop has something you'd like.
For pre-ordering the game at GameStop, you'll get to take home a double-sided poster. Each side features artwork from New Pokemon Snap, with one side showcasing a collage of photos, and the other featuring an island scene. You can pre-order the game here.
