A credit card is required for all orders. When an order is placed on the system no payments are collected until The University Book Store actually ship the order. The system does check with your credit/debit card provider to make sure that there are sufficient funds available to cover the total amount of the order (your financial institution might list this fund check with a “Pending” notation). That happens even if you have entered a gift card with a balance that covers the entire cost of the order. When your order is shipped the system will apply the gift card first. If that covers the total amount of the order your credit/debit card will not be billed anything. If the gift card covers a portion of the order total your credit/debit card will be billed the difference. Only if the gift card has no balance would the entire amount of the order be billed to your credit/debit card.
