When processing orders, we place a temporary authorization hold on your gift card for a slightly higher amount than your estimated order total. This small difference accounts for potential changes in the final total due to special requests, added items, items replaced at a different price, and actual weight of items. If the authorization hold exceeds the amount on your gift card, we charge the difference to the credit or debit card you entered at checkout. Your gift card and/or credit or debit card will only be charged for the total of the items delivered to you.
