I was in my local Asda store in Ipswich earlier today and while paying for some Blurays the lady told me they had Harry Potter and the Half Blood Prince for only £7. She said she thought it was a misprice and it would go back up when they realise.
Misprice or not I thought that was a good price for a Bluray full stop.
The Original price was £19.71
Picture will be uploaded shortly - yes still struggling with it!
