They put a post on facebook that they had technical issues that they believe have been solved.
I cancelled the free trial that came up in my account when I tried over the weekend to get the special. Then tried to sign up again. When I choose "get this option" (to pay the full $120 and get the kit and coupon), it just takes me back to a class page. I sent them another message.
The Canyon Creek kit is sold out, so only two choices left. Both are made with solids, which do nothing for me, so guess I will pass on the offer now, even if they do get it sorted. If anyone should want one of those kits without the unlimited Craftsy, they are both on clearance for about $80.
