Pam Bondi, FL Attorney General has this to say:
Florida law prohibits extreme increases in the price of essential commodities, such as food, water, hotels, ice, gasoline, lumber and equipment, needed as a direct result of a declared state of emergency. My office has received more than 40 price gouging complaints. My investigators are following up on these complaints, contacting the consumers and businesses, and making site visits to the businesses, where appropriate, to ensure that if there is a potential pricing issue, the business is advised immediately so that it can change its practices and make refunds. 
The majority of the complaints received involve gas pricing, motel rates or tree removal service fees. Anyone who suspects price gouging during this declared state of emergency should report it to my office by calling 1-866-9-NO-SCAM.
