Tons of people join JV Giveaway events (the ones where loads of freebies are given out). As a contributor you get exposure and build your list. As a member you get loads of free stuff which can be a cheap way to get an education.
Then there is the third type of person who benefits ...
The Product creator with an affiliate program. Who joins the Giveaway and checks out your freebie ... your system and then joins your list. Then emails you recommending his (or her) product to put on your download page.
How easy is that!
Can't believe I'd never seen it before. Suppose that's like the best business ideas - simple and easy to implement.
