I listed my paperback on Amazon for $17.86, now it is being sold for $17.62. Not a big difference, but I just don't understand what's happening here. I am not selling it anywhere else. Is there a lower price somewhere Amazon is trying to match? If it is going to keep dropping, then I'm glad I started with a medium-high price. Anyone else experience this? Note: I did list the book for expanded distribution, so that may figure in, though I don't think I've had any exp. dist. sales yet.
