9/8/25 Update
For the first time in over a decade, we’re lowering the cost of shipping! Starting September 12, Posh Post drops from $8.27 to just $6.49—our lowest rate since 2017.
Why we’re doing this
USPS recently announced industry-wide rate increases on Priority Mail shipping. With input from our sellers and a shared goal of keeping shipping accessible, we partnered with USPS to find a better path forward. The result is a new, lower shipping rate that benefits both buyers and sellers.
What’s staying the same
You’ll still get all the perks of Posh Post, our exclusive shipping system:
- Flat-rate shipping on every order—no guessing, no hidden fees
- One label for anything up to 5 pounds
- The ability to use your own packaging
- Prepaid label and QR code options
What’s changing
Orders will ship via USPS Ground Advantage, with delivery in 2 to 5 business days.
This means that starting September 12, USPS Priority Mail packaging can no longer be used to ship Poshmark orders. Starting October 12th, USPS will charge a $5 fee for using Priority Mail packaging. This fee will be deducted from your redeemable balance.
If you already use your own packaging, there’s nothing you need to change. If you’ve been using Priority Mail materials, simply switch to non-Priority Mail packaging. To make this transition easier, Poshmark sellers will have exclusive access to free USPS Ground Advantage boxes.
Due to the contract process, we unfortunately weren’t cleared to announce this update until today. While the timeline is shorter than usual, we hope you share in our excitement about this price reduction.
This is one of our biggest updates yet, and a meaningful shift toward bringing more shoppers to your closets, leading to stronger sales. Together, we’re not just selling fashion, we’re building its future.
