Vinh spent a grant total of US$30 to purchase 15 Powerball lottery tickets at Dehoff’s Key Market in San Mateo City, California.
He hit the Powerball jackpot on Sept 25 and elected to receive the payoff over a 30 year period rather than in a lump sum.
Vinh is a nail maker and has been playing the lottery for the past five years.
He said he was elated and surprised to receive the huge reward and added he has not made any plans on how he is going to spend it yet.
The Dehoff Key market also gets US$1 million for selling the winning ticket.
