PEF Sport Tickets

Has anyone ever bought tickets through PEF for a sporting event?

I bought tickets to the Celtics game this Sunday and the email with the tickets looks sketchy. I'm nervous that I'm going to show up to the game and be told my tickets are fake.

This happened to me once when I bought tickets to a concert through the pef membership benefits website, who has a no refund policy despite their 100% satisfaction guarantee lol
