Typically, customers can expect to receive a refund from Zappos within five to seven business days after the returned item is received at their fulfillment center. The length of time may vary depending on a few factors, including the return shipping method used and the processing time for the return. Once the return is processed, Zappos will initiate the refund to the original payment method. Customers should also keep in mind that the time it takes for the refund to appear in their account can depend on their bank's processing times. For the most accurate and up-to-date information, it is advisable to check the current Zappos website or return policy page, where further details can be found.
