There are two places near where I live that I will allow me to do a book signing with them. One is the public library, the other is a local grocery store that is eager to take on local authors. I've done two signings at the library, and sold very few books both times. I haven't tried one at the grocery store, but I'm hesitant to try because people generally don't go to a grocery store to buy books. What do you think, should I stick to the library or try the grocery store?
