A 70-year-old woman celebrated winning the lottery by buying another ticket. She won again.

WILMINGTON, Del. – A woman in Delaware hit the lottery twice within a week, claiming two six-figure rewards totaling $400,000.

The 70-year-old woman, who wished to remain anonymous, purchased two $100K "Ultimate C Instant Game" tickets from a gas station near Newark, Delaware, and found that one was a winner.

This win was her biggest since she began playing the Delaware Lottery seven years ago, she said.

While driving home after picking up her earnings from Lottery Headquarters in Dover with a friend, she bought three "Serious Money" tickets from a convenience store to celebrate the occasion.

One of those tickets was a $300,000 top prize winner.

“My best friend was the first person I told about winning the $100,000 top prize, and she came with me to claim it,” the woman said in a Delaware Lottery statement. “When I scratched the $300,000 winning Serious Money ticket later in the day, we just sat there in disbelief. It was absolute insanity.”

The pair returned to the lottery headquarters, for the second time on Oct. 20, to claim the $300,000 "Serious Money" prize, bringing the woman’s total winnings to $400,000 for the day.

The woman plans to put most of the money into her retirement fund.
