We have a money back option - with our SP Points. Aside from the referral commissions, we also give a portion of our earning back to the users when they purchase something from the website.
For every dollar spent on the SharePage, we give 10 SP POINTS.
For every 1000 SP points, we give back $10 CAD redeemable when it reaches $100CAD
You can view your SP Points from the Master Dashboard - SP Point page.
