Amazon's 2 for £10 has some nice stuff in, worth a good sort through. Lots of Tartan blu-rays (I myself finally got around to upgrading Sympathy for Mr. Vengeance and Lady Vengeance) which seem to keep a higher than usual price. Certainly much higher than £5 each!
MovieMail have a great 2 for £15 offer on too. Lots of great stuff. I picked up La Ceremonie and Holy Motors, but own the likes of Berberian Sound Studio, Himizu, Tabu, Once Upon a Time in Anatolia, Le Havre, We Need To Talk About Kevin, Confessions, The Woodsman and the Rain and Weekend, and can heartily recommend, especially at £7.50 each.
