I was actually thinking what Sean said, a PS5, but I've had other consoles before, so I dunno if that counts as already purchased. Though I think they've all been gifts. Except for the 3DS, which may not count because it's a hand-held. Also, actually the first thought that came to mind, is a pretty rock or meteorite that I don't already have. But I've bought other rocks, so I don't know if that counts.
