I usually get asked if I will trade an item on Poshmark….and the answer is always no. Why may you ask? Well, its an unauthorized transaction on Poshmark. Why does that matter? Because unauthorized transactions are not Poshmark protected. I am not saying that I do not trust my fellow Poshettes, but with those selected few, you may not get the item you actually traded for. Lets say that you wanted to trade for my Michael Kors Selma bag for a Rebecca Minkoff cross body.
