The only requirement here is that you have a MotorsportReg account. Once you've created an account you can purchase the event 3-Pack. The credits acquired from the purchase expire at the end of the calendar year.
IMPORTANT NOTE
Though you were not required to be an SCCA member to get this 3-pack, you will either need to be an active SCCA member before registering for an Event, or register as a non-member. This 3 pack does not cover in full 3 non-member registrations, only in full 3 "member" registrations. The weekend membership has not been factored in. The system will let you pay $55 in credits to do a non-member entry. During your third event check-in however, you will not have enough credit to cover the third event in full.
