Is anyone using the ground advantage boxes/envelopes for eBay? When I ordered mine the order taker read a statement asking if I understood that the supplies were to be used for ground advantage shipping only. Which is weird since Poshmark only has ground advantage shipping.

I'm curious if this has been confirmed anywhere? I can't find the answer online.

So most of us re-use boxes, bubble mailers, polybags, packing materials, etc. when we can. So Poshmark has these exclusive shipping materials that are only supposed to be used for Poshmark orders.

We have all shipped something in a used Amazon box. What do you think would happen if we shipped something in a used Poshmark USPS mailer?

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
