A while back I had a sales leaflet posted to me from a local warehouse. I spotted boxes of dishwasher tabs for £5 (I can't remember the exact price, but extremely cheap for the size). In the warehouse the same dishwasher tabs were marked up at £10. I questioned this with the sales staff and was told that the leaflet had been printed wrong and the dishwasher tabs were actually £10, though they did offer to sell me one box at £5, which I was happy with. I was just wondering what the legal standing on this is. If a leaflet is printed showing an incorrect price, is the store legally obliged to sell the product at the price shown on the leaflet?
