Free USPS Ground Advantage Shipping Boxes
My understanding is that Poshmark did this because they discontinued priority shipping and sellers were complaining that they did not want to have to buy boxes. Poshmark handles shipping differently than most places do. They charge buyers a flat rate and they provide the shipping label free of charge to the seller. Up to now it was always a priority label but now it is a ground advantage label, which means no free boxes from the post office, and the sellers were pissed off. The main complaints I see now is that the boxes were not available soon enough. It's interesting that they managed to get USPS to produce the boxes, instead of just buying them themselves. Maybe they will eventually become available to all sellers for free, or at a low cost. More on reddit.com

What is USPS Ground Advantage? Pricing and Requirements
April 1, 2026 - An important thing to keep in mind is that USPS Ground Advantage is a fitting option for boxed and rigid shipments rather than flat and flexible envelopes. USPS also mandates that all letter-like pieces that are less than 1/4 inch thick have a minimum of 5 inches in length, 3-1/2 inches in height, and 0.007 inches in thickness.

Sometimes, the cost of mailing a package based on dimensional weight will be less than if you were to base the postage on the package's actual weight.

September 9, 2025 -

Got through to USPS (800-610-8734)

The representative I spoke to was well aware of the free "ground advantage" boxes and mailers. All the following come in packs of 25. I was able to order 75 of each box and 100 of the mailers. If you need more, you can, that's just how much I wanted to start off with.

Box 1: 12 x 12 x 8.5

Box 2: 14 x 7 x 5

Poly Padded Bubble Bag: 12.5 x 9.5

Paper Padded: 14.5 x 20,5

Polybag: 14 x 17

I was told it would take 7-10 days to arrive.

Of course, they will ask you for your Poshmark closet name. Hope this helps! I was hung up on about 10 times, and finally on hold for about 30 minutes, and had a very helpful and pleasant representative.

And according to the following link on usps website, ground advantage is eligible for free pickup
