Roy Gudka emailed to ask about the rules on splitting multipacks on both Coca-Cola and sweets. As it so happens I have written about both Coke and choc bars recently so I was able to tell him that it was okay with the former: around the rim it says ‘multipack cans’, but it doesn’t say it cannot be sold separately.
But with the latter you have to be sure that all the product information is on the packaging. With a multipack of Mars bars, for example, the outer wrapper has all the required information on it, but the five bars inside do not. They say ‘not for individual resale’ in two places on each bar and they also say ‘allergy information: see pack’. So it means the whole pack has to be provided.
