On our site we have a free membership (which offers limited access) and a paid membership (which offers full access). We want to add a short-duration (5 days) full-access membership so users can see what is available to full members. But, we don’t want someone to repeatedly sign up for a 5 day membership, to avoid paying for the full membership. Is there a way to prevent a user from signing up for this more than once?
We’re using Paypal Pro Forms.
