I meant LOWER price. :rolleyes:
Can’t speak for Mike, but for me, craft magazines, sheet music and bound music books, and vintage children’s books do quite well for me. They’re rarely worth a lot of money but I do make a profit on them. I don’t get a lot of textbooks, although I have sold a few.
Ah. There is a Pioneer Village just outside Phoenix as well.
I rarely trade-in books to Amazon as if they want it, I can sell it for a greater profit, but will sometimes trade-in books and DVD sets, video games, CDs, etc. that I can’t sell. I buy most everything on Amazon myself and can always use the credit for labels, shipping supplies, etc.
Fiction does not sell as well as non-fiction on Amazon. I’ll sell in any category. I sell a lot of general history, military history, business, science, technology, professions, etc. Textbooks are seasonal but of course sell well.
The most niche titles are the ones that sell for the highest amount. A book on how to surf will not sell as well as a book on philosophers who were also surfers.
I will always look at any title where I think, “Who would want a book about THAT?” (guaranteed money-maker) or where I have no idea what the title means (ditto). Best sellers, self-help books, etc. generally are not worth selling for me. The more obscure, the better.
Although there are no WWI veterans still alive (I think), and WWII vets are growing older and older, WWI books still sell well. It’s a topic of perennial interest as we wonder how the hell it happened. There is also a lot of interest by military historians in how flexible German battle strategy was compared to French, British, and American war strategy, and how the seeds for the “blitzkrieg” theory of war began in WWI. Again, very specific books do better than overviews. I just sold 3 copies of a book about sniping from the trenches in WWI for over $100 each.
On average, how many books do you sell per day?
Someone from the Pixar headquarters ordered one from me today. 
It will be da bomb if they use it as the basis for a movie, years from now.
