If you are in the UK (or anywhere for that matter) and you are not able to access the website would you please let me know. You can just leave a comment here. I have let the website host know that there is a problem but I don't know how widespread it is. If you wanted to buy something in the sale, and you can't access the site, let me know and I can work it out through email with you.
Sorry for the inconvenience!
