Stamps.com has just released a new PDF Guide that helps sellers understand the dimensions for all the free Priority Mail boxes that the USPS provides. Many sellers will likely only be aware of the Flat Rate Boxes and may not be aware that the USPS has 29 total boxes available for Priority Mail.
The guide displays the various box sizes and weight limits for every Priority Mail box and envelope the USPS provides. It’s another useful resource for anyone trying to get the best value shipping deal for their ecommerce business.
Stamps.com have also created a series of downloadable guides that seek to help you save money on the myriad of USPS services. Check them out.
