I asked this over at KS but didn’t get a response and wanted to know before I finish my form.
Are the hexbooks going to be available later? If so, will the coupons be usable on them for Dwimmermount backers?
I may reply to the KS comment too as I go through them today. The hexbooks are produced by Albatross Press, which will be handling sales of them outside the KS, most likely through Lulu. So it should be possible to get them later but not to use a coupon.
