This is the best price I have found for this boxset, 4400 season 2. The next best price is £14.99 and at some places its still £49.99. This is an excellent boxset with 2 dvd's and 13 episodes on them. Season 4 will be showing on TV in summer this year. don't forget quidco. Some of the best prices on eBay are £17.99 plus p&p.
Enjoy and have a great day.
