We do try to be as upfront about this as possible, and our apologies if you came to this page with any misunderstanding.
ShowMojo's annual plans are "annual" because the leads on the plan are usable for an entire year. Once the leads on an annual plan are used up, the plan does automatically renew.
We try to capture this with as clean language as possible on our Annual Plan Pricing Page: Annual plans last up to a year, and auto-renew when the duration or lead limit is reached.
