USPS has NO IDEA of the new FREE Ground Advantage packaging!
My post office actually implemented this already and told me about it. They had boxes ready for free. So I guess it depends on your USPS location but mine is on point and they have always been so awesome and friendly. More on reddit.com

September 8, 2025 -

Hi!!! As an avid poshmark seller Iโ€™ve religiously been using the priority mail boxes. Iโ€™m currently in a pickle because I really donโ€™t have any brown boxes laying around and I sell a lot of designer purses and mugs that I canโ€™t just throw in a polymailer. Any recommendations on the best priced place to get brown boxes for??? Any insight helpsโค๏ธ

Answer (1 of 3): Small and medium boxes which come in different shapes which you can pick up at your local post office for free. If you arenโ€™t sure the mail clerks know which sizes Poshers use so ask for clarity. Make sure the mailers state priority in red on them.

r/poshmark on Reddit: USPS has NO IDEA of the new FREE Ground Advantage packaging!
September 9, 2025 -

After calls dropped dozens of times I finally got through to a postal worker and she admitted that Posh sellers have been blowing up their lines today and they had NO CLUE of the update!

Poshmark has promised the following (I highlighted the important bits) https://blog.poshmark.com/ :

Poshmark has partnered with USPS to provide complimentary Ground Advantage shipping supplies exclusively for Poshmark sellers. Packaging options include a variety of polymailers, padded mailers, and boxes*.* 
To order your packaging supplies, please call 800-610-8734. Please note that you will need to provide your closet name to USPS to confirm you are a Poshmark seller.

Rest assured, USPS is prepared for this transition and ready to support requests from our community.

I particularly love the last line about USPS being prepared for this (REST ASSURED - ha!)!

I found out that the USPS customer service reps have an internal chat group where they can reach out to each other to help with information about things they are getting calls on and the supervisors and team were all in the dark on this.

Call lines are open M-F 7am - 11pm (1-800-610-8734). Lets help each other out and report back if anyone has any success getting the free packaging Poshmark is promising. Otherwise, this means the discounted shipping makes selling MORE EXPENSIVE because we are now providing shipping materials from our own pockets.

****--------------------------------------------------------------------------------------------****

10:15pm EST Update - Finally got through and the phone system seems to have been fixed to not drop calls since the prompts seemed to be different. The rep said they have been overloaded by Posh sellers but they are working through to get to everyone quickly.

Supplies options includes different polymailers, bubble mailers and boxes. Limited selection but its better than nothing.

I asked what they do with our closet info and she said they are supposed to look us up to verify that we have a closet.

I said that the Posh community is generally really great and that I hoped everyone was being nice and patient with them and she said yes, most were lovely. SOOOO ---- lets represent our community well and let them know how appreciative we are of what they do to support us in our sales!
