The shipping process is fully robotic and orders are pulled and shipped quickly in 7 different warehouses across the US and then dropped in sealed USPS, UPS and FedEx containers for pick-up on the next business day. Once pulled, orders cannot be stopped, however you can return orders for refund unopened if you have changed your mind. Tracking normally is sent / updated within 48 hours of pick-up. Delivery is normally 7 business days or less. It may take longer in rural areas. Weekends and Holidays do not count as business days and have no pickup, movement or delivery.
Covid 19 Update — We have seen some slowdowns and backlogs in package sorting and scanning by UPS, Fedex and USPS caused by worker shortages and closed facilities due to the Covid 19 Pandemic. Some UPS and USPS hubs are no longer scanning all packages, as a result some tracking will show nothing until delivery.
