Good lord, I hope this doesn't sound like a rank newbie question, but ... Assuming someone purchased a Clickbank product through your affiliate link, and you promised a free "cheat sheet" in return. The cheat sheat has Step 1, Step 2, etc until Step 10. What's the best way to discourage freeloaders from buying the CB product, getting your cheat sheet, returning the product to Clickbank for a refund, and then using that same cheat sheet as a sweetener to get others to purchase through his / her affiliate link? What do you advise? Should the cheat sheet be in a PDF format? Or a password-protected site? I think you can see I'm really new at this - I don't even know the right questions to ask. Any help would be truly appreciated!
