Paperbacks only on Amazon?

I didn't know this because I shop at both places, but there are some big fans either of Barnes and Noble or Amazon, and they don't shop at the competitor's store.

I've recently been asked why my paperback is not available on Barnes and Noble, so I thought I'd address that here. I have toyed with the idea of opening distribution to other booksellers, but I've been holding off. Why? For a simple reason: I have to charge more for the book if I expand distribution to account for other stores' cuts. (Literally, if I kept the price at $9.99, I'd owe money on each sale.)

For those of you who prefer BN, I do apologize, but you are welcome to purchase directly through my website using Paypal, and the cost–including shipping–is roughly the same as what I would have to charge if I expanded distribution.

I am not trying to be difficult. I just can't see charging $15 when I have the option to sell for $10. I regret that I may lose sales due to inconvenience, but I really want to keep my prices low, especially in this economy.
