Less than a week after announcing his office would sue Dollar General, Ohio Attorney General Dave Yost filed suit against Family Dollar.

Both lawsuits allege the companies advertised goods at one price on shelves and then charged another, usually higher price at checkout.

The lawsuit cites violations of Ohio's Consumer Sales Practices Act, claiming Family Dollar listed false prices on products and engaged in bait advertising.

Family Dollar has been owned by Dollar Tree since 2015 to reach low and lower-middle-income households.

A news release from the AG's Office on the Dollar General lawsuit said error rates of 16.7% to 88.2% were found at 20 Dollar General stores throughout the state. The Ohio Department of Agriculture allows stores to have up to a 2% error on overcharges.

So far, Yost's office hasn't released error rates for Family Dollar.

Anyone who suspects unfair business practices can report them to the Ohio Attorney General's Office by calling 800-282-0515.
