That is me also but as I wanted to make custard where people in the house aren't feeling well I needed more than normal. I noticed a 1/2 gallon was $1.85 but a gallon was on sale for $1.58 same house brand.I have no idea what the price of milk is per gallon. We don't drink milk. I keep a small container of 1or 2% on hand for cooking. What I pay, I have no idea.
