Doubt it. There was a similar case with a dutch online shop, and they also tried a lawsuit. Somebody even started up a site to collect for the legal fund, but I suspect that they used their collection to buy themselves the TV at the normal price instead.
How can people seriously think that it is fair to sue the company for making a mistake and forcing them to loose hundreds of thousands of pounds? Fair enough if you get a bargain, but to still try and take when the mistake has been realised is just cuntish IMHO.
