During your purchase, you will be able to select any saved payment method* you prefer for your 1st payment to be charged to. However, subsequent deductions for your 2nd and 3rd payments will be charged to your "Default" payment method instead.
For example: If you've opted to pay with "Credit Card (A)" during the point of purchase but "Credit Card (B)" has been tagged as your "Default" payment method, your 2nd and 3rd payments will be charged to "Credit Card (B)" instead.
*The option to pay with your linked bank account is not available during the point of purchase. If you've opted to pay with a credit/debit card during the point of purchase but your linked bank account has been tagged as your "default" payment method, your 2nd and 3rd payments will be deducted from your bank account instead.
