I'm not sure why this is the case, but I had one of the largest non-book-release sales months in a while. The largest I can remember offhand.
It includes sales of:
19 copies of GURPS Martial Arts
More than 10 copies each of DF15 and Low Tech Companion 2.
And 21 copies of DFT3.
Nice! I'm not sure what occasioned it, but it's very nice to see. Thanks guys!
