I bought 4 boxes of Roxul sized 2' x 4' x 12", with sheets inside where some were 2" thick and some 1" thick (and they've got 4" thick, too, if you want it). Got them for a reasonable cost on Amazon, and they arrived well intact. Made for some nice corner and wall bass traps. Just get on Amazon and search for Roxul.
If you don't like the itch, the recycled denim stuff works just as well, albeit at a greater cost. Bought that at a Menards. It was very nice to work with for stuffing in between some installed hat channels that suspended my drywall. No itch (but a dust mask is still definitely recommended)!
