Hi @Konstantina Manioudaki4 Sine you have purchased a standalone quest, you can get the first year of membership for $300 for the first year instead of the regular $499/yr.
You will have LIFETIME validity for Duality quest since you purchased it separately. For all the quests you get access to through membership, you will have access as long as subscription is active.
Please send a request for $300 to the support at https://support.mindvalley.com2.
All the best. Thanks.
