The entire stock of Firehawk and Flight Deck shirts was not on sale. All of the SOB shirts were out there, and can't be found anywhere else in the park. People use the Nick sale as evidence of NU leaving- what's different about this?
Now, about The Crypt- how much do you really think they spent on theming? Most of it was recycled Haunt stuff, anyway. And, when they added the theming, The Crypt still had an eight flip cycle, and wasn't in as bad of a state as it is now.
