What are the most profitable things to sell here on DP? I have tried to sell a couple of things with no results. I would prefer advice on e-books.
Selling ebooks here is a waste of time.. Go ahead give it a try but I doubt you'll sell a copy or two. Try with a service and stick to your fees, don't lower it but be prepared to ignore dozens of PM's where people are asking to give the service for free or half the charge. Ignore them all and stick to your rules when you're capable delivering a high quality service (or product).
