I will offering 5 plr bonuses to those who purchase my affiliate program opportunity, now some of these people are also interested learning how to create their own ebooks to sell online so I will be offering a ebook creation checklist as one of the bonuses but then I wish to try and upsell or just sell them 9 of the other checklists related to ebooks

What I am confused about is how to go about selling them the other 9 checklists after they get their 1st checklist free and become a subscriber

3) Is a membership site necessary to sell my plr products
