Go to the Orioles team store at Camden Yards for the best selection. Also, if you’re a birdland member (even partial season ticket plan) you should be able to get a discount. I did some holiday shopping at the team store and was very pleasantly surprised that my membership got me 50% off! Birdland memberships start at like $200 so it’s something to consider when you do the math on how much you’ll save on merch and concessions during games.

(I don’t work for the Orioles ticket office I promise)
