How much money is a gallon of milk now?

The price of milk can fluctuate depending on several factors, such as the region, store, brand, and current market conditions. As of my limited knowledge up to January 2022, the average price for a gallon of whole milk in the United States was approximately $3.90. However, this information may be outdated, and it's always best to check the latest prices at your local grocery store or through online retailers.
