I think that SFI has given many incentives to become a Executive Affiliate or a Team Leader, that is the genius with this program. If you are offering non SFI gifts what would be your gain. If someone is needing to get to a certain level it usually is that they are lacking money to place an order. So I would suggest that the only incentive that you would want to offer would be SFI related, such as a gift certificate or T-credits.
