A purely anecdotal story:
Recent events (and promotions) enticed me to check out some PDF material.
Found something that looked interesting for $4.95 (50% off) and bought a download.
After a few days of perusal, I decided I definitely wanted a hard copy.
Checked with the FLGS, not in stock. The print run has apparently been exhausted, and the publisher is not planning on reprinting material several years old now. (I did pick up some stuff while I was there... but that's another thread.)
So I do the dirty thing and check Amazon. Nope.
A more exhaustive internet search turns up a few copies, and I order one at a decent price.
Something about the purchase nags at me a little. A bit of deja-vu.
So I browse back to paizo and check around a bit, a stumble upon this thread (again).
Turns out my PDF-inspired hard copy purchase was made from Titan Games in Battle Creek, MI.
Which I just found amusing, considering the original post in this thread.
