It's got to be some sort of cockup but I've just bought 4 of these tyres for £261.36. They should be around £130 a piece. Don't even need tyres at the moment so put a fitting date for march next year. Try it!!
I don't think that's true there is something in law that allows for errors, enough places in the past have recalled the offer but as a goodwill gesture they should honour it.they cant make you pay the full price, they have to honour the price it was advertised as that is a contract. however if they do turn around and say that YOUR tyres were part of a fire or whatever and give you a refund, then that a different story. i would get them to change them now and ask to keep your old tyres.
