I think it may be a problem with their website. When I just looked at prices before I got the different pricing when logged in and not. I tried again, logged in and still got the price of £500.76+vat for that ultrasonic quoted, but this time when I added it to my basket for possible purchase, then the price reduced to £468+vat, with no explanation as to why the price changed. I also noticed that when logged in, I get cheaper quoted Kilo prices for silver sheet than when not logged in.
