Price Gouging Prevention Act This bill makes it unlawful for any person to sell, or offer for sale, a consumer good during a federally-declared emergency at a price that (1) exceeds 10% of the price charged by similarly-situated sellers of such good during the 120 days before the emergency was declared. However, such a price increase may not be a violation if the increase is (1) attributable to additional costs incurred by the seller to provide the consumer good, or (2) is not more than 10% greater than a combination of the total cost incurred by the seller and the customary price markup of the good. The bill grants the Federal Trade Commission and state attorneys general the authority to enforce compliance with the requirements of this bill.
