Still working on my review, the new set is the individual seasons in keepcases, they're even shrinkwrapped individually with the top tags and "hype stickers", in a box which is the only thing you'd gain from buying it instead of each season by itself. (The locker set has more bonus discs.)

Season 6 is $12.99 on Amazon and at Best Buy.

Saw this at Walmart the other day for $49 and change, or $49.96, can't remember...Might have to bite at this price, since Amazon has it for $62ish I believe.
