That shouldn't be a problem as the account has been designed for flexibility.
Simply enable our Part Pay option and pay at least 1/4 of the Statement Balance to keep the account up-to-date.
Please note a 2.5% fee will be added to your account if you enable the Part Pay option. If you pay off your Statement Balance in full, there will be no fee.
Once the account is paid off, there is no fee to keep it open until you make another purchase.
