I have read in the forum that selling Ebooks doesn't pay well because they are very saturated. My question is could they be a good supplement? I have some niche stores that are getting sales like one on rv parts, but I don't know enough about the products or the subject to be able to write an insightful post. If I put an Ebook for sale on say how to buy rvs do you think it will turn people off? Should I just look for articles to put on my site?
