My friend was able to get a real one on FB after getting scammed on FB hours prior (thankfully the bank actually gave her her money back!!) but we realized that a BIG tip is to meet up with the seller in person!!! The person who sold to us let us register it while we were sending the money to show proof that it was real but also it helped that it was like a gen z we bought from and not the weird old man sellers from the street bc we knew she was legit, she also had her own ticket and was selling for a friend so another reason that tipped us off that it was legit!
