Normally, we ship within 5 business days from receipt of payment. You need to order enough time in advance for the part to be packed so that it can be shipped by the mail day. If it is ordered on or after the ship day, it will be mailed the week after.  Post Office shipping days are Tuesdays/Wednesdays. FedEx/UPS shipping days are Thursdays/Fridays. WE DO NOT SHIP ON WEEKENDS OR HOLIDAYS.
