Did you know you can freeze milk? I like to stock up on milk when it is 10/$10 for the half gallons. I buy enough to last for awhile so I don't have to buy it when it is $3/gallon. This has saved me a lot on milk. I put it in my deep freeze. We never run out of milk for our cereal! Some people like to empty a little milk out because it expands, but I never do and it is fine.
This week milk is 10/$10 for half gallons at Fry's and Albertson's. It is also quicker to defrost a 1/2 gallon than a whole.
