I finished my ebook I'm going to give for subscribing but then I wanted to also sell it on Kindle for like $1.99. The only thing is, I thought wouldn't someone be upset buying it and then visiting my site and subscribing, only to get the same ebook they just bought? So I thought, why don't I put at the end of the book that if they visit my site and subscribe, I will refund the $1.99. Should I do it, or not worth? Figured I'm giving them an incentive to subscribe and it is my way out of the issue of them seeing me giving it away too. Thoughts?
