My hubby and I drink milk with dinner, we always have both Chocolate and white milk in the fridge. I would say we go through a 1/2 gallon of each a week. So about a gallon a week.

1/2 gallon of Chocolate milk is $2.49
1/2 gallon of 2% milk is $1.99.

Wow... looking at the price difference now that I typed it out....why don't we just buy chocolate syrup to put in our white milk!?!? (duh Angie...)
