Charged on poshmark for using priority box. Used my own poly mailer
I got this email today. The dress was sent in a solid black poly mailer that I purchased on Amazon. When I replied with this and my tracking number, poshmark just repeated the same thing. This is what i found on seeing if it was sent ground advantage and my tracking has the 346
The Service Type Code (346): The next three digits (346) make up the Service Type Code (STC). In the USPS master routing database, the 346 code specifically maps to a USPS Ground Advantage package with standard tracking.
