What’s the difference between 30-day and monthly access?

30-Day Once-Off Subscription: Purchase a voucher every 30 days via EasyPay or PayFast. You will receive a reminder to renew your subscription a few days before it runs out. Activation can take up to 24 hours after renewal. You can load up to 6 vouchers at once, and they will activate consecutively as each 30-day period expires.
Monthly Recurring Subscription: The subscription is automatically renewed every month, with payments deducted from your credit or debit card via PayFast, provided there are sufficient funds.
