r/poshmark on Reddit: List of FREE Ground Advantage Shipping Supplies
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

What is USPS Ground Advantage? Pricing and Requirements
April 1, 2026 - Delivery Speed – USPS Ground Advantage is ideal if you need reliable 2-5 business day delivery across all 50 states. Saturday Delivery – Included at no extra charge, Saturday delivery is beneficial for businesses that want to ensure free weekend deliveries. Delivery Coverage – If you frequently ship to PO Boxes or APO/FPO/DPO addresses, USPS services are your best option as UPS and FedEx do not deliver to these addresses.
