Yep, that's the one, though I'm wondering if it's a better deal to order from the American site (just change "co.uk" to ".com" in that address). It goes for $17.95 new on Amazon -- so if they don't clobber you for shipping...
The movies that get the real in-depth treatment include a lot of the ones you might expect (the Saw movies, Cabin Fever, Hostel, Wolf Creek, Rogue) as well as the Ginger Snaps series, Cube, 30 Days of Night, the French flick Inside, and some others.
Thank you for your interest, ZS!
