Don’t overlook selling your books to bookstores – especially if you’ve built in a wholesale price.  Most bookstores (both chain and independent) have a local interest section.  Contact all bookstores (don’t overlook the “biggies” like Books-A-Million, Barnes & Noble, etc.) by phone to set up an appointment.  Arrive on time, with either an Advanced Reading Copy (ARC) as an example or the actual book in hand.  Best of luck!
