Cheap Milk

I don't know if a lot of you go to BJ's Wholesale or Costco. But I go to BJ's for things that usually does not go on sale and I can get cheaper compare to grocery stores. One of them is MILK. A galloon of whole milk in BJ's cost only 2.29 compare to A&P 3.99. The coupon booklet that they recently sent out has a coupon for $2 off any 2 dairies. So I end up paying $2.58 for 2 two galloons of milk!!!
