The Sports Museum, and the Pro Shop are where it's at.

Like any stadium, the stores are all much more overpriced compared to shopping online. There's a great new pro shop that opened up on the 2nd floor right where you scan your ticket. Any and all gear you're looking for will be there if you want to buy something at the game.

The Shop at the Garden is really expensive but they have everything you would ever want with a four leaf clover on it.
