FYI I am PG so may be over empathizing due to hormones 
Was out earlier today, to buy work and craft books and school supplies for my boys who are both HE. Anyway, I was trawling through and wandered through the novel sections and I just felt really sad, especially for the lesser know authors. I just thinking, imagine it's been your dream to write a story, sometimes your story, you find an agent and get published and then there you are in the bargain bins. It's funny because I don't feel that when I go into supermarkets, some strange part of me thinks that that must be quite the opposite as SMs normally buy based on demand and imagine being thought of as being as essential as carrots ect. No, it doesn't make sense, I know.
Maybe I feel like that because I always wanted to have a go at writing but was never brave enough.
