Missouri Attorney General Chris Koster says the drugstore chain Walgreens is overcharging customers on about 20 percent of the items it sells.
Koster has filed a civil lawsuit against the Illinois-based retailer after undercover investigators in his office visited eight stores across the state, including two in the St. Louis area.
Koster says in some cases, the price posted on the shelf was for a sale that had long expired. In other cases, the retailer promised discounted prices for rewards members, then charged the regular price at the checkout.
Koster says anyone who feels they were overcharged, or who witnesses deceptive pricing should call the Missouri Consumer Hotline at 1-800-392-8222 or visit his website.
In response to the lawsuit, Walgreens issued the following statement:
"We have a 112-year history of acting in our customers' best interests, and that will continue to be our focus. While we won't comment on the complaint itself, we were disappointed and disagree with the attorney general's comments. However, we are prepared to have a constructive dialogue about the issues he raised and address any appropriate concerns."
