(WISN) — A new study finds people in Wisconsin pay more for beer than half the country, including Illinois.

The study, done by online credit group simplythrifty.com, finds people in Wisconsin pay about $3 more for a case of Miller Lite or Bud Light than people in Illinois.

“We found the prices from national or regional retailers in up to 10 ZIP codes in each state for a 24-pack of Bud Light and Miller Lite,” said a description on their website. “The ZIP codes chosen were a mix of urban and rural areas to get a representation of different parts of each state. We averaged the prices of the two beers together and rounded to the nearest cent. The numbers reflect prices only, taken from the retailers, and do not reflect any additional taxes or fees, such as recycling fees.”

Based off the study’s findings, people in Wisconsin pay an average of $18.22 per 24-pack of Miller Lite or Bud Light. Wisconsin ranks 25th in the country for those prices. Illinois is cheapest at $15.20 per 24-pack and Alaska is the most expensive, with residents paying about $31.21 per case.

MillerCoors told our sister station, WISN, they sell their beer at different prices within each state, according to each area’s market.

“There’s no single factor that explains the difference but it is a factor of the market, which includes retail competitive intensity, supplier competitive environment, and [substitute] products,” said Marty Maloney, a MillerCoors spokesmas.

Essentially, people in Wisconsin are willing to pay more for their beer.

Wisconsin alcohol retailers are required by the state’s minimum markup law to markup their prices by at least 6 percent, but experts at Otto’s Wine and Spirits say that doesn’t have as much of an impact as people would think.

“That markup is so minimal that obviously you couldn’t run a business based off of that,” said Timothy Berger, who controls pricing at Otto’s.

Berger also said Miller Lite temporarily raises their prices every February by about 20 to 30 cents per case of beer, but then drops the price again in the summer months.
