I don't know, If they released a perfect Supes, I'd order 5, not 6 but close enough, we don't have a single good classic Superman figure in 1/12 so if one ever comes out; I.WILL.HOARD.
So I'd get 1 for the office, 1 to play with, 1 for the detolf, and 2 backups, of course most people who order that quantity think about resale, not to collect.
Most online toy stores have limits between 3 to 6, 2 is waaaay to restrictive, but most online toy store aren't toy manufacturers with artificial scarcity in mind to create the illusion of "exclusivity".
