I ordered the first 4 Wrong Turn's on Blu-ray earlier this week, since Amazon had them all for $24.99
as a deal of the week.
I decided to go ahead and order Part 5 as well...it sounds fun like the 4th film.
If you're wondering how those first four in the bundle pack are packaged, they're all the individual retail versions, and all are double-sealed without any cut-outs or other such imperfections. Part 4 comes with both the Blu-ray and the DVD, so it's basically a 5-disc bundle set. It works out to just a little over $6 a movie.
