when you do a search on the home page for all 1/6 hot toys currently for sale, it doesn't come up. do it for the silver centurion specifically, and the search jumps to the exclusive page. i had to log in to my account, go to the product archive search, then search there within the result to find it. i always thought sideshow website's search engine was weak, but this looks like they are pushing the exclusive over the regular by making the regular so difficult to find. i guess they figure it's the same price, and you get a crushed helmet exclusive.
getting back, i have also seen like here, a website buried regular version while the exclusive was still for sale. when the exclusive was gone, the regular was listed sold out too. maybe because it had been sold at retailers all along and they expelled their stock.
