lol i think they stole the product photo from bazaarbazaar
edit: how are 365games with US based stock pre-orders? i notice they're selling uta 3 for £4 less than VG+ (not including shipping) and it comes 4 days earlier too, i think i pre-ordered ZTD from them last time but i've since forgot what it was like timewise
