These are not the USPS Priority Mail packaging options you’ll get for free instead, these are packaging options that USPS provides and calls ReadyPost.

If you walked into your local Post Office recently, you’ve likely noticed an abundance of brown packaging for sale near the counter. ReadyPost Boxes and Envelopes Are NOT Free USPS Packaging Since all USPS Priority Mail boxes and envelopes are free, they are one of the most popular packaging options for shippers on a budget, and small businesses just getting started that haven’t decided to invest in custom packaging.
