Shameless self-promotion:

When you buy a boxed set of Swords & Six-Siders (a rules-lite 1d6 only fantasy RPG inspired by BX & T&T) through the end of December, you get either another set, or an adventure and extra player's book for free.

The OSRIC Player's Guide is available at 30% off through December on lulu.com, so combine it with a lulu coupon for serious savings:
