FTC and 20 US states sue Dollar General over overcharging

The US Federal Trade Commission and 20 states have sued Dollar General, the country's largest dollar-store chain, accusing it of routinely charging shoppers more at the register than prices shown on shelves, tags and ads. The 95-page complaint, filed in federal court in Nashville, says the pattern persisted for years across its more than 20,000 stores and affected millions of purchases.
