Discounts on Memberships
Unfortunately at the moment Gumroad memberships do not have a "Temporary Discount" feature where members could, for example, get their first month free, then pay $5/month.
Any discounts applied to memberships are therefore permanent. Whatever rate someone starts paying on a membership product is what they will always pay for that membership.
It might still be useful though, to offer the equivalent of a 10% off offer code to your first 50 members, or use discounts as a call to action for your fans.
Not to worry though, we are hoping to build out a feature that would accomplish "temporary discounts" soon.
