Okay, this set used to be an awesome deal. However, amazon droped the price of the original individual boxsets and forgot to adjust this price as well. Here are the prices:
Season 1 19.97
Season 2 24.97
Season 3 24.97
Season 4 24.97
Season 5 26.67
This is a difference of 20.30. So right now, it is better to get each box set on it's own. Hopefully amazon will correct this and price these sets around a 100 bucks. That would be tasty.
Edit: Apparently Amazon saw thier mistake and rather than lowering this price, they uped the price of all of the other seasons back up to where they were. Poor show amazon. Very poor show.
