If we send out waitlist invites on the same day as or the day before a presale is occurring, new subscribers are not eligible for this presale. It states in your invite email that you will not be eligible to participate in any presales happening within the next 48 hours. Sorry for any disappointment! You will be eligible for any future presales provided you remain an active subscriber.
