Michigan Attorney General Dana Nessel has sent Menards a cease and desist letter alleging that the company has raised prices on face masks, bleach, and other products.
The complaints started at a Menards location in South Haven last week.
"Large corporations must also play by the rules, and my office will work diligently to ensure this state's consumers are treated fairly and not abused by businesses seeking to unlawfully jack prices up to line their pockets with profits at the expense of the public during this time of great need," Nessel said.
Nessel said Menards is exploiting fears over the coronavirus and doubling the prices on cleaning products, as well as tying purchases to in-store rebates.
As of Tuesday afternoon, Menards had not responded to Nessel's allegations. The company has 10 days to respond to the attorney general or risk legal action.
