So, I have been an avid OfferUp user for local purchases/sales (over 100+ sales and 50+ purchases), but typically didn't dabble with shipping much. I found a user that had a cheap MacBook Pro (who also had a number of reviews and prior sales), who which auto-accepted my full-price offer of 500+30 shipping.
The label for said item was created, but then a few hours later their account was deactivated, thus barring me from leaving feedback or opening a buyer's protection claim. I created a ticket via OfferUp iOS application with the transaction ID ahead of time, in case of any funny business (i.e. the box they ship has rocks in it, and after two days pass my funds are released from escrow).
Thanks in advance for any advice for dealing with this!
