The local charities in our network get referral codes to share with their membership. For each member that joins Upside with the charity’s referral code, Upside will donate $2.50 initially and then 2¢/gal for every gallon that member buys. Super cool, right?
All you’ll need to do is enter the promo code when you sign up. If you miss the box to enter the promo code when you first register, you’ll have a second chance to enter it. Just click on the menu, Profile, and enter the charity’s code in the promo code box.
