You can expect your grocery bill to keep going up.

The U.S. Department of Agriculture says milk is costing more across the nation.

It sold for an average of $19.40 per 100 pounds in June. That's up $1 from just the month before.

It's even more expensive in Wisconsin, where the average price last month is about $20 and $0.80 per 100 pounds. That's up nearly $2 from May.

The USDA says prices for corn, soybeans, oat and hay also are up.

Corn averaged an estimated $6.20 per bushel in Wisconsin in June and $6.12 per bushel nationwide.

That's almost twice as much as it cost last year at that time.
