I don't think you can sell on both platforms. Once you accept the quote from FP, you ship the bag to them, you receive payment and they sell the bag on their own. The bag is no longer yours. I'm confused how the seller can have the bag posted on FP and Poshmark at the same time. It means she no longer has the bag in her possession and she's selling the bag??? It doesn't make sense. I would never proceed if I sense something wrong.
