pricey movie disc
£15 for a newly released movie doesn't seem that pricey to me. It's about the same as a trip to the cinema but without the sticky carpet experience.
A well known high street retailer has hundreds of BRDs for sale in a 5 for £30 offer. That makes them £6 each. They currently are doing 5 DVDs for £20 (£4 each). And of course they look better than DVDs when played on your fancy-pants OLED telly-box.
