Nice! MSRP was $199, and according to my email archives, I paid $139, so I definitely don't feel bad about buying it. TRU was always good about putting the big sets on sale pretty regularly.
But knowing what it goes for now, I would feel bad about busting it open just for shits and giggles... Same with the Halo Countdown and NMPD Pelican Air Base, both of which fetch 4x what I paid for them. Don't want to sell them, can't bring myself to open them. ¯\_(ツ)_/¯
