When you go to register for one of our events that participates in our group buy program, you are given the option of purchasing multiple "tickets" at one time which you can then share with your friends who will be joining you. Once those tickets are purchased, you'll receive an email with unique codes that you can distribute to your friends who must then complete their individual registration. These codes cause our registration forms to deduct the price of entry from their registration since you will have already paid for them at the discounted rate.
New this year, once you've purchased enough tickets to reach the first discount tier, you'll also be given a coupon code that you can share with any of your other friends who might suddenly get FoMo and want to join you. It'll be good for the same discount that you got when you purchased those tickets. It's a nice way for you to be able to share the experience with even more people.
