How does the "Refer a Friend" program work?

If a friend refers you to Tinkergarten, they may send you a code for $15 off. This code is honored the first time you register for a Tinkergarten season. The code only works once and cannot be combined with any other offer.

Once you register for a Tinkergarten class, you'll have the opportunity to invite friends, too! Tell a friend to use your personal code when they enroll in any full season of Tinkergarten. They'll get $15 off the class price and you will receive a $15 refund on the current season’s order, with the maximum refund value equal to your original purchase price that season.
