Thanks to Potlepa for spotting this one - I agree with his sentiments that it's hopefully not a mis-price and just a special offer on this boxset.
This is the Hex Season 2 DVD BoxSet for £7.99 delivered from 101cd.com. The next cheapest price online is £12 at HMV, so this is a pretty good price!
Details: Sky One's popular supernatural teen drama returns to DVD with the release of the entire second season. The series stars Christina Cole (“What A Girl Wants”), Colin Salmon (“Alien vs. Predator”), Jamie Davis (“Footballers' Wives”) and Jemima Roper (“As If”). In this latest series the demon Azazeal (Michael Fassbender, “Band of Brothers”) is moving ever closer to his nefarious goals, with Cassie's baby playing an integral role in his plans. With the help of the ghostly Thelma (Roper) and new pal Ella, a time-travelling witch (Laura Piper, “Reign of Fire”), Cassie sets out to stop Azazeal at any cost.
