Next cheapest appears to be £27.98 at Amazon.
HMV also have Seasons 2 and 3 for £12.99 each (next cheapest £17.99 each at Amazon), and also the complete boxset for £37.99 (next cheapest and in stock £56.98 at Amazon) - but that is actually a couple of quid more expensive than buying them separately.
The town of Roswell, New Mexico, has been haunted for decades with accounts of a looming alien presence. The popular television series ROSWELL takes that concept one step further, as aliens become everyday teenagers. Four alien-human hybrids (Shiri Appleby, Jason Behr, Katherine Heigl, Brendan Fehr) have been sent to Earth to wait for the day when they'll return to their planet and save their race, but they don't really now that yet. But for now, their battles are the everyday struggles that normal teenagers must face, like spots and school. Blending straight drama with elements of sci-fi, ROSWELL is an engaging drama that works on numerous levels. This release contains every episode from the show's first season.
