I really wanted to learn how they wrote copy so well and made me want to buy now. So I emailed the Rhodes brothers and simply asked. They gave me a great list of resources to look up.
But lets be honest, most of use are lazy (me to) and I need another couple of books in my library like I need another hole in my head.
The solution - I simply went and searched the WSO forum for every WSO put out by these three. Then I printed each of the sales letters out and started making a swipe file.
Now I can see how they write their headlines, bullet points, and more - all for free.
So instead of having to buy books I can just model a sales letter after one of theirs that catches my eye.
It helped me and hopefully it will help you as well.
PS: Rachel Rofe is another one to watch as well
