I hope all goes well with the sale. I’m sure it will, but it has to be in the back of your mind.About a month ago I sold something on ebay for which the buyer gave me feedback immediately after purchase. She complimented the fast shipping time, the great packaging and how it was just as described. I hadn't even shipped yet! It terrified me but I shipped it anyway. So far so good. But there is always the chance that she could do a chargeback in a month or two. That is what I hate about ebay. I guess technically someone could do a credit card chargeback for an item purchased on Poshmark months later. I have no idea how Poshmark would handle that. They have my bank account info for deposit. I wonder if they have ever tried to snatch anyone's money and if that would be legal.
When you have a return on Poshmark, if all goes well, you get your money back and Poshmark pays the shipping. On ebay, you lose your shipping costs both ways and will likely be forced to accept a return even when you know the buyer is lying.
I can answer about chargebacks on poshmark. I sold an item a few years ago on poshmark and agreed to a buyer’s request to sell $500 of the price through poshmark so the buyer would get verification of authenticity and the rest through direct payment via PayPal. This goes against Poshmark policies, so I take full responsibility for everything that happened afterwards. The item was verified as authentic and shipped to the buyer, but the buyer contacted me and said the item was smaller than she expected (though as described). She filed a claim with Paypal and they denied her. Then she did a charge back through the credit card that she had used on PayPal and the money was removed from my PayPal account. Paypal said there was nothing they could do. This was over a month later and I had already withdrawn the money, so my PayPal account was put in negative and I had to add the money from my bank or any future payments processed through PayPal would be taken to cover the negative balance. It was my own fault for going outside of the rules, so I accept what happened. She also tried to file a chargeback with her credit card for the amount paid through Poshmark, but either it was not approved or Poshmark ate the loss, because that money remained in my account. So in the end I was only left with the $400 (my share of the $500) that went through poshmark, and the total price was just under $4k.
