What you can do is promote the ecourse first and once the person subscribes forward them to the sales page for the resell right product. It takes the average person atleast 7xs to see an offer before they buy. Creating an ecourse is an excellent way to people to buy as you can keep reminding them about your product.
** A Word About Freebies **
I would stay away from products that say they can be sold or offered for free. You’re going to have an upset customer if someone pays money for a product and then finds out that others are giving it away for free. I use these as subscriber bait. They sound impressive because they can be sold. So use them to get people to subscribe to your ezine or your ecourse for the product.
