I'm about halfway through with my next novel. I'm wondering if I should self-publish it. My shorts collection gets more sales at $.99 than the books my publishers have published. My publishers price my books between $5.99 and $6.55. I feel if I could lower the prices, I could get more sales. But I wouldn't have the professional editing and promotional opportunities that my publisher now does for me. I'm wondering what I should do. Any advice?
