Nah, the math ain't mathin there. $6 per person for food and drink (assuming they each get 3 items), that's $24. That is inexpensive to feed a family of four, but it's certainly not cheaper than buying at the grocery store and staying home if you're doing an apples-to-apples comparison. You can get a package of hot dogs for $6, a package of popcorn for $6 and a 24-can case of soda for $12, and you'll have enough left over to do it all again, so you get at least double the volume of food for the same price - and that's not counting the $4 for adult tickets and any fee for parking or transportation at the game.
