From the Office of the PA Attorney General:
Recent events in the Gulf states have caused devastation affecting hundreds of thousands of consumers. Hurricane Katrina has also caused market disruptions affecting consumers far from its path. Unfortunately, in these situations there is always the possibility that disreputable businesses may try to illegally profit from the circumstances. The Office of Attorney General wants any Pennsylvania consumer who believes that a retailer in our state has tried to take advantage of the recent events to contact our office.

If you believe you that a gas station has illegally raised its prices, please complete the complaint form from the link below and return it to our Office or complete an online complaint form. Be sure to provide all relevant details including: the gas price and the grade of gasoline, the name and location of the retailer, and the time and date when you saw the price in place. If you purchased gas from the retailer, save your receipts and provide copies with your complaint. With your help, we can protect Pennsylvania consumers from price gouging.
