The Florida Lottery said Matthew Anderson purchased a $30 ticket for "The Fastest Road to $1,000,000" game from the Circle K, located at 12001 Gulf Blvd in Treasure Island.
The store will receive a $2,000 bonus commission for selling the winning ticket.
Anderson chose to receive his winnings as a one-time, lump-sum payment of $790,000.
His win comes on the heels of another Bay Area resident's recent jackpot.
Last week, 64-year-old Michael Landcaster of Seffner also claimed a $1 million prize from a scratch-off ticket. It was his second big lotto win in two years.
