George and Barbara own a pharmacy together. At the end of the financial year, George decides to get rid of the surplus stock with a big sale. George advertised in the pharmacy window the exclusive brands at a 50% discount. He presents these brands alongside the cheaper, similar products in the displays throughout the shop. Barbara is concerned that the displays are misleading as there are five times as many cheaper products than exclusive products to sell. George is not concerned. Advise Barbara if her concerns are justified. 

Have they breached any laws?
