I have just received an email to this effect. Anyone who wants me to forward it to them please give me a private message with your email address. I will not spam you as I have no reason to!
Perhaps if you join their mailing list you too will be sent this offer!?
If anyone can upload my email to the web in a printable format please get in touch and I will forward you the voucher too. I probably could but I'm very busy today.
