Hey Bax - we can confirm this is legitimate. BSI are one of our Merch Store partners.
If the link isn't working, we suggest you email BSI Customer Services as it seems to be working for others. Let them know what country you are in and that you'd like to buy one. Congrats on being invited to nab one of the very few still available - hope they sort you out quickly so you can get your copy.
Wow sorry for the ping then :-P and thanks for the reply! It works from my pc, oddly, just not from mobile.
Yeah they just fixed the link after I sent that apparently!
