You can view all your available Gift Card Codes in the "Gift Card Program" area of your Back Office, under "Gift Cards Available". These codes can be sent directly from your back office to someone's email or copy and pasted and shared via text, Facebook messenger, email, or even printed off and given as a physical gift.
You can also give gift cards to members of your team to share with their new enrollments. The Gift Card will work and apply the discount when they make their purchase. The person's whose website they ordered from would be the member that is their sponsor, and would receive credit for their purchase.
Once a Gift Card is used it will show up in the "Gift Cards Used" area of your Back Office.
