I'm sure news traveled fast so the site is overloaded. It was in stock, limit of 2, $19.99 price point plus $6.95 shipping for them. I ordered a couple more, just in case.
Also had the shirts up but didn't see the poster. Just three items on the site that I could see before it crashed. The black CIII shirt, maroon CIII shirt and the Vader figure.
edited to reflect the case issue. Only a couple of bucks extra then, as they were selling the cases for $3.
