Someone's messed up at iTunes! Chances are the mistake will have been rectified by the time that you read this but right now (June 19th, 1.45am) the complete collection of Downton Abbey is only £2.99 on iTunes (UK store). My guess is that it should be £29.99 but someone at iTunes HQ has mistyped the price. Get it while you can!
