I've never used StubHub to sell, but I've used it several times to buy. For concert tickets, it's always been straightforward. Pay your money and an envelope arrives a few days later via FedEx. The one time I used it to buy NFL football tickets, I ordered on the morning of an afternoon game. They had me drive to a small hotel near the stadium where they'd taken over the lobby. I presented my ID and they handed me my tickets. Easy!
