The 9-disc Alien Quadrilogy on sale at Costco for $31.99. In the immortal words of Private Hudson, "Game over, man. Game over!" That's an offer no self-respecting geek could be reasonably expected to refuse.
(I just wish somebody would tell me why the Fox execs felt the need to make up the word "Quadrilogy" when the the much cooler and already-extant "Tetralogy"could have been used.)
