Went to Asda last night after midnight and ask if I could get HSM3, I was told they normaly sell it after 8am but she would get the manager. Manager came and went round the back and got a copy for me and told me just to pay at the checkouts. Went to the self scan and it came up as 0.02, paid as quickly as possible and walked out with a huge grin.
Well chuffed, HSM3 for 2p.
They obviously hadn't updated the computers to the proper price.
