Hey there!

I have to be honest, I haven't tried this. But I own the products recommended 
here.

Before this "sale" (in quotes because the front-end is cost-free), I had planned
on building a 2-step funnel where the landing page was the opt in for this "viral"
report (for which I would get the email address and the lead would get the report
for free), and--once subscribed--they'd be taken to the "pre-sell" page where 
there would be an affiliate link (mine) for Viral PDF Brander...so you could do it
yourself.

I'd drive traffic via paid ads.

But, to be 100% honest, this is easier for both you and me. I don't have to create
a funnel, and I'm happy about that. I won't be creating any ads, either. Dennis
Becker did all the hard work :)

So, get it here - it's a good case study on how to grow your subscriber list and 
make sales, either of your own products or affiliate products.
