Likewise I’m not seeing persuasive evidence to support a case of ‘intent to defraud’ (on the part of the people ordering them) for speculatively attempting to buy at the price advertised, even whilst possessing more than reasonable grounds to suspect that price was incorrect.
Where is the evidence of ‘wrongful or criminal deception’ involved here, it’s just people trying their luck, plus the seller isn’t going to be in ‘ignorance’ of the incorrect pricing on the website (which is one of the ‘tests’), and there is adequate remedy available to him anyway under contract law to not sell them for £0.00 just because he’s offered them for £0.00.
(Funny how much you can remember when you try hard enough (err, that is assuming that I’ve remembered/interpreted it correctly) although it hardly matters either way, my speculative interpretation is only “something you’ve read on the internet”; nothing like the law at all). 😉
