Warmup pucks

Hello all. I will be traveling to St. Paul to see my flyers play on Thursday(my dad was born in Minnesota and I still have family there but I grew up in Philly). This will be my 10th arena and one of the traditions I have is buying either a warmup puck or a puck that displays that current date with the matchup on it. I was wondering if there was a particular place in the arena that would have these pucks . Thank you in advance, if there is anything else I should check out let me know. Also, take care of Bobby Brink, he was one of my boys.
