Here’s the answer:
SFI provides the professional Websites for marketing products on the Internet, as well as all necessary sale support services, such as customer service, payment processing, and product shipment — all at no cost to the affiliate.
For each sale generated, Affiliates receive a commission. Additional commissions can be earned by building and leading teams of affiliates.
There is not magic, just a platform to use. I encourage you to join and start reading the Launchpad lessons in order to understand how SFI works and the programs you might be interested in promoting. Go check it out for yourself, it is free to join, no obligation and you can opt out anytime. http://joinme.gomoreinfo.com
