WH Smith are having a DVD sale on at the moment.
In-Store only, as i checked online, and they were far more expensive.
Compared to other Online retailers, most the others couldnt match.
Happy Gilmore - £2 (nearest is HMV @ £4 if you can get it delivered, i gave up after a month previously)
Human Traffic - £2 ( nearest is DVD.co.uk @ £3.95)
Donnie Darko (Single Disc Directors Cut) - £2 (Nearest HMV @ £5)
Green Street - £4 ( Only match Amazon @£4 + Del)
Those are just what caught my eye, there were more there including 2Fast 2Furious @ £3-4 and some trashy looking horror films around the £1 to £2 price range. Some people like them.
