Walmart is accused of advertising and offering goods without the intent to sell them as offered in its Washington, D.C., stores, violating the District of Columbia’s Consumer Protection Procedures Act, according to the midsize firms that filed the suit this week.

The Jan. 23 class action alleges that Walmart mispriced items in stores through the D.C. metropolitan area, with shelf-tag prices on items being lower than the prices charged at the register.
