You can purchase vouchers for more days if you wish, however, once this is redeemed on your account, it will override the existing active plan.
For this reason, we recommend waiting until your plan expires before redeeming a new voucher.
Alternatively, if you don't want to worry about buying new vouchers every 30 days or so, it may be easier for you to purchase 90 or 365-day plans or enabling Auto Renewal. With Auto Renewal, the new voucher cost will automatically debit from your credit or debit card. This can be done from your customer dashboard.
Our standard 90 and 365 day Prepay Plans also save you money compared to buying our standard 30-day Prepay Plans every 30 days.
You can have a look at our Prepay Plans here.
