He would have no >legal choice<
It's one of hundreds of thousands (maybe millions) of products which are 'poor value for money' there is >no law< which states a product must not be an exorbitant price.
In this case a customer accepted the goods on offer for the price & took over as the legal owner. The owner went on to use the goods as described.The goods lasted for at least as long as they were garanteed for so in law, the goods were 'fit for purpose'.
As far as charging exorbitant prices for goods its perfectly >legal< buyer accepts the contract 'offer', if I have a box of Swan Vestas matches & offer it for sale at £3,000 anyone is free to buy them at £3,000, it is not illegal for me to sell a box of Swan Vestas matches at the price neither is it illegal for someone to buy them at .£3,000
