I'm going to Skepticon 3 this year, and I've been thinking about ordering 10-15 copies of my book. I'm not sure if I will, but here are the pro's and con's, as I see them.
Might get to give a few copies to the speakers, who might read it and review it, and a review would expand my audience.
Might get to sell a few copies, which would offset the expense of the trip.
Might get seen as a shameless self-promoter.
Might spend over 80-100 dollars and never see anything for it, if I'm not able to sell any copies or give them away.
Might be very awkward to find a way to sell the book. Do I just tell people that I meet about it or what?
So: What do you guys think? Should I do it or not?
