I ordered 4 tickets for a Tim Minchin concert. I was shown a shopping cart that said they would cost £198 (far too much - but I was in a mad hurry and they kept flashing up pop ups about how many people were booking and how few minutes I had left!)... when the order confirmation came through it came to over £700 - with a load of extortionate booking and delivery charges added. This cannot be legal. My visa credit provider initial response is that there is nothing they can do. I will not be letting it rest there.
