A 30-day notice to cancel your membership is required. No pro-rate for mid-month cancelations.
30-Day Notice Examples:
Cancel Jan 1 – Membership would end Jan 31 (30-day notice puts cancelation date to the end of Janaury and prior to the billing for February)
Cancel Jan 5-Jan 31– Membership would end February 28 (30-day notice puts cancelation date past the billing for February so they pay for the full month of January).
