A couple of things may have happened:
  1. In addition to using your friend's referral link to purchase your Ava, you also need to take note of the discount code that appeared at the top of your screen when you first opened her link and then manually type this code into the Discount box at checkout.
     
  2. The referral program discount code only applies to Ava 1.2 purchases. If you tried to purchase a strap 1.2, unfortunately, this does not qualify for a referral discount.
