Went to local (ashton) B&Q yesterday and bought a Yale home alarm security system HSA6400 premium wireless system. They are advertising 50% of all alarm & security items at the moment, banner states price will be deducted at the till. The shelf advertised the yale system as being £99.99, so when it didn't go through as discounted 50% I told them that is what the advert on the aisle states (50% of shelf price). They informed me that it had already been deducted 50% - the shelf price but had to give me another 50% as that is what they advertised. I also got a carbon monoxide gas alarm for £5.49 rather than the £11 it should of been.
