When I was younger, I pre-order Ocarina of Time from gamestop, but weeks later I heard about the "Gold" cartridge and called in to change my pre-order to that. I was told that no such thing existed.
So the damn Zelda comes out I bike several miles to go pick it up.
When I arrive, I am told that no "ordinary" grey cartridges came in, only gold ones. So I would have to wait till my ordinary one got in....
