1) The problem → In a one-time payment there's currently no way to add a free trial, just an expiration date
2) Why is this important → I need a free trial for this one-time membership.
3) What's your plan B → I'm going to create two memberships, Membership A for the length of the trial with an expiry date. Create a coupon for Membership A and add a button for upgrading to Membership B. (Taken from this forum: https://forum.memberstack.io/t/free-trial-for-one-time-payment-memberships-options/1196/4)
4) Possible solutions we could build for you → Like the monthly / annual memberships to have a free trial.
