If Congress doesn't agree on a new Farm Bill before the end of the year, you could soon pay up to $7 or $8 for a gallon of milk.
That has shoppers and farmers in Alabama worried.
Right now, you can pick up a gallon for about $4.
If the current law expires, the country will go back to the 1949 law.
Under it, the price of milk would almost double.
David Gilmer owns a dairy farm in Lamar County.
He's worried he could be out of business soon.
"They're not going to pay for it and when they don't pay for it we lose our market, and if we don't have a market, we're history," said Gilmer.
If an agreement can't be made, you probably won't see prices change immediately, but those prices could be a reality after a few months.
