We use both UPS and USPS to ship orders. Sometimes, we use a UPS service called Mail Innovations. This allows us to keep shipping costs lower for customers, while offering a great delivery option.
Mail Innovations works by UPS fulfilling the bulk of the delivery process, with the final stage of delivery is done by USPS. This means you will track your order on the UPS website, but your order will ultimately be delivered to you by USPS.
