Here you'll be able to enter your membership pricing.
FYI, anyone who purchases a membership at a price point you set, if you decide to change it in the future, they will be charged the price they purchased. Example: you set the price at $30/mo but realize it's too little & want to raise the price to $90/mo. Everyone who has purchased at $30/mo will continue to be charged at $30 unless they cancel & repurchase. Every new purchase will be charged at $90/mo.
