Gilt credits issued as a result of gift cards and returns when the original order was paid by a credit card do not expire. These will remain in your account and will automatically apply towards your next order.
All other credits, such as return credits for purchases using credits and promotional or marketing credits typically expire between two weeks and one year from the date of issuance, unless otherwise stated. Please be sure to read any correspondence regarding promotional or marketing credits carefully, paying particular attention to the expiration date as these credits cannot be re-instated.
