A successful author with a lot of sales (and I see at least three in the thread) is a successful marketer of written work. There are a lot of factors that go into deciding how to price articles and what rights to offer. I offer usage at a discount on everything I have for sale because if the buyer will buy usage I know I can post it elsewhere for revenue share or just use it on one of my blogs.
Thank you, Jadedragon, and Happy New Year! This is a good idea!
I like to give usage rights because I can sell the same articles again. I already sold twice two short articles. I didn’t think about posting them somewhere else. You opened my eyes!
