You can always pay your plan in full early. Simply login to the Shopper Portal and select the button that states 'Pay Outstanding Balance (Credit/Debit)'. This action will charge the full outstanding payment from your chosen credit card.
If you wish to pay your full balance with a different card, or with a debit card, select the button that states 'Pay Outstanding Balance (Credit/Debit)' and then select the button that states 'Pay with a different card.' Enter the new card details and then select the button that states 'Pay Outstanding Balance.'
Note: You can only update your card 2 times in any 24 hour period.
