I just noticed (thanks to +joseph browning ) that there is a 30% off all Lulu.com purchases coupon code floating around.
30% off is pretty huge and will go a long way to adding books to your gaming library.
The code is:
Ends October 10th at 12:59 PM
(Joe also has 20% off on the Advanced Adventures Compendiums (vol. 1-3) - lots of adventuring for a very fair price)
Note - there are no affiliate links for Lulu. I'm sharing this because it's freaking awesome! :)
Add suggested purchases for your fellow Taverners in the comments section. They'll appreciate it as will I.
