In the newsletter that went out Sunday, Nicholas said:
I mentioned above collecting email addresses, and I have been encouraging early adopters of the RMU pdfs to sign up for DriveThru notification emails. I sent a wave of discount coupons out on the Tuesday after Gen Con, both for Spell Law to all early adopter pdf purchasers, and to those who filled in the physical and web form for Core Law and Spell Law. If you did not receive the coupons, please contact Colin.
Tuesday after the con would be Aug 8th.
(By the end of the con we actually had run out of both Core and Spell Law, softcover and hardcover. Only had one display copy of each left.)
