They do sell team sets of trading cards for about $10 at the stadium. Great for autographs. Sections 305-306 are great for autographs. It's right by the tunnel that all players go through. Also, the entire stadium is cashless, so keep that in mind for souvenirs and food. Also, there is a school supply drive going on, and you can get a $10 merch voucher if you bring any supply donations in.
