🚚 Lower Shipping Costs on Poshmark + My Experience with USPS Supplies

Poshmark has rolled out a new flat‑rate shipping price of $6.49, down from the old $8.27. That’s a $1.78 savings per package, which really adds up for resellers who ship often.
This change comes through a partnership with USPS, moving from Priority Mail to USPS Ground Advantage. It’s not just about lower costs—it’s about smoother shipping, better supplies, and a more streamlined experience for sellers like me.
WHAT HAS CHANGED?
| 📦 Old Rate | ✨ New Rate | 💰 Savings |
|---|---|---|
| $8.27 | $6.49 | $1.78 per package |
- New service: USPS Ground Advantage, with delivery in 2–5 business days.
- Packaging update: Priority Mail boxes are no longer accepted. Sellers must use plain packaging or USPS Ground Advantage supplies.
- Free supplies: Call USPS at 800‑610‑8734 and provide your Poshmark closet name to order free Ground Advantage mailers.

My Personal Story- I am LOVING the new supplies
When the change first rolled out, I’ll admit—I was nervous about losing my stack of Priority Mail boxes. They had become part of my reseller routine. But once I ordered the Ground Advantage mailers, I was pleasantly surprised.
The supplies arrived quickly, and I love how lightweight and flexible the mailers are. They make packing clothes and accessories so much easier, especially when I’m bundling items. The best part? They’re free, and ordering them was as simple as calling USPS with my closet name.
Now, I keep a neat stack of Ground Advantage mailers in my shipping corner. It feels organized, efficient, and honestly a little exciting—like I’ve upgraded my shipping game. Every time I pack an order, I’m reminded that I’m saving money. I stay compliant. I give my buyers a smooth experience.
For me, this isn’t just a shipping update—it’s a small but meaningful improvement in my daily workflow. And as someone who thrives on systems and efficiency, I’m loving it.
THIS IS A WIN FOR ALL INVOLVED
Lower shipping costs, reliable delivery, and free supplies—it’s a win for sellers and buyers alike. If you haven’t tried ordering the new USPS Ground Advantage mailers yet, I highly recommend it. They’ve made my Poshmark routine easier, more affordable, and a lot more fun.
