Thanks for the comments, everyone. I have included the URL of this thread in my reply to her. And here is part of the rest of what I wrote, explaining why I thought her book was over-priced:
>>>I am not saying the book is by default worth less just because it is self-published, but to say it is AS POLISHED a product when it by definition is not---those publishing houses pay their editors a salary for a reason---is not fair. What you are offering is a self-published title, not a commercial title. It therefore costs less to produce. Take off $2 for the paper/shipping/warehousing that does not exist for your book, and take off another $2 for the salary you are not paying to an editor, marketing department, art department etc. and your self-published book is worth $4 less right there, no matter how good it is. And readers know this. If you check out your competition on Smashwords, most sell their books for $0.99 to $1.99 (and at $2, there is your $6 mass market paperback price minus the $4 I accounted for above, and this is therefore a fair price).>>>
If she's reading this thread, I just want to reiterate that I wish her well and am by no means trying to be unfriendly. She asked, I am explaining
