I don't complain about the prices of concessions because if you want to bring your own food or drink you can. But they don't allow sunscreen which is also okay, but they should sell sunscreen at a reasonable price then. I was sitting in the sun yesterday and used sunscreen before the game but went to the Nats store to get some since I couldn't bring it in. The prices were outrageous. A fairly small can of SFP 50 was $30 bucks. A smaller can of SPF 30 was $15.
