You can, because there are no rules against it. In fact, there are no rules at all. Which is odd. However, I personally do not want to see listings in the sub - if anything, maybe list your poshmark?

Please don't.

I've seen people list their Mercari shop name but I don't believe this can be used as an actual resale shop.

I don't believe there are any rules against it.

You’d probably have better luck on Poshmark or Depop. Idk if many people here would be looking to buy items

There is no protection or buyers or sellers here. It would not be a wise platform to try to sell on.

You can do mystery boxes on Poshmark I’ve sold a few.

I appreciate everyone being kind about not wanting selling going on here. I won't be doing that lol
