A retailer advertises a range of its cameras as being 'new', when in fact, they are demonstration models that have been used in the store for several months and placed back in their original packaging which has been resealed. A customer buys one of these cameras and later discovers the truth about their condition. Explain whether there has been a misrepresentation by the retailer and if so, what remedies the customer might have against the retailer. Use case laws where necessary
