Let's say an item has a RRP of £200. Cost to manufacturer is £150. Mainly interested in an answer for the UK - but rest of the world would be good to know - but can a company sell that item for £70? I know it sounds stupid but I'm testing something as part of an analytics setup. Is this legal to do. Another thing from curiosity is, can someone legally sell that product for £1 and make a loss? Thanks!
