Following advice I found online, I have begun giving away samples of my books. For Connie Cobbler: Toy Detective I printed the first three chapters back to back in booklet form. I left them at various stores (with permission, of course) that cater to children and their parents. For my e-books Miss Mary Pennynickle's Tales of Torment for Toddlers and Miss Mary Pennynickle's Fairtales of Foreboding I paperclipped sample stories to mini-posters and gave them to friends who go to goth clubs, midnight movies, and independent music stores. These have proven to be very successful. This works best for the Miss Pennynickle books. I've seen a large uptick in sales at the end of the weekend once the parties have slowed down.
I have placed my book for sale on eBay. I offer it at cost to me and can personalize autographs. Charge around $2.50 for shipping and my money is made back.
If anyone has any suggestions for promotions, please let me know.
