If you have funds in your Gift Certificate Account, you can use those funds to
purchase course registrations. At the checkout stage, an extra box will
appear. Ticking this box will apply those funds from your Gift Certificate Account.
Please note, you will still have to select another payment method if there
is not enough in your Gift Certificate Account to cover the cost of your purchase.
If you have more funds in your Gift Certificate Account than the total cost of
your purchase, the unused balance will be left in your Gift Certificate Account for the
future.
