I hope this is the right place to post this.
Years ago. When I was about to release my first product. (Ebook) I strugled at creating sales letter. I had no idea how to make profitable one. And I had not enough money to hire a copy writer.
Then I found this awesome Ebook: "Psychology Of Selling".
It taught me about everything I needed to know about sales letters. When I bought the Ebook. I got MR rights to it.
If you have problems creating a sales letter. Don't hire copy writer just yet. Read this first. It is free for Nb members.
