Can I use my store credit to partially pay for an existing order or the balance payment of a preorder?

For example, using $600 in store credit and paying the remaining $100 with a card for a $700 total?

Answer: Store credit can be used to pay off an order, but partial payments combining store credit and a card are not supported. Instead, you will need to top up your store credit balance with an additional $100, bringing the total to $700, and then use store credit to complete the payment.
