Once logged in go to "Profile Settings" then scroll down to "Payment Method."
From here you can add a new payment method by clicking "Add Card" then entering your information in the pop-up.
Once you add the new payment method, make sure to select the new card as the default. If you do not make it the new default, we will not charge the updated card.
If you experience any issues, please use Goggle Chrome and use an incognito/private window. You can open an incognito window by clicking "file" in the upper left hand corner.
