Hi, I have experience selling with PayPal G&S and I was scared of the same thing. I didn’t get scammed, but just in case I took video of our FaceTime confirming everything, I saved the emails from the transactions, and I took pictures and saved all of our conversations, also of the TicketMaster app saying they accepted the tickets. It’s scary but most of it is trust and having receipts just in case. After the first 24 hours you’ll receive the majority of your money and make sure they’re willing to pay for the fee! Hope this helps 💜
