Paper Check: Most paper check orders will be marked Paid by 4:00 p.m. CST the same day the check is deposited; however, we cannot predict how long itll take USPS to get the check to us. Paper checks take 3-5 business days to clear with our Billing Department from the date on which they are marked Paid. Once cleared, most paper check orders ship within 2-4 business days. Depending on shipping method, paper check orders should be delivered within 1-5 business days of shipment.
