But there will be no champagne lifestyle for Susan Crossland – not only is she staying in Dewsbury and still shopping in Netto, but she's allergic to bubbly.
As Susan celebrated her win at Dewsbury District Golf Club on Wednesday, she was careful not to get any splashes of champagne on her skin.
Susan, from Ravensthorpe, suffers from anaphylaxis, which means touching alcohol or foods such as butter could be fatal to her.
Rather than a glass of bubbly, she said, she would much prefer a cup of tea.
The 44-year-old housewife won a share of the Lotto jackpot on Saturday evening, but didn't check her ticket until Sunday morning.
She said: "I sat in a daze until Sunday afternoon, I really couldn't tell you what I was doing, then I eventually called Camelot.
"It has been a whirlwind ever since and the whole win feels very surreal at the moment!"
But the win obviously didn't go to her head as the next day Susan went shopping in Netto and husband Michael, 39, went to work filling milk bottles at Kershaw's Dairy, Mirfield.
Michael said he was determined to carry on with his job.
He said: "I would get bored sat at home and we couldn't live together seven days a week!"
The winning ticket was bought at Ravensthorpe Milco and the numbers were the ones Susan's late father used to play.
Susan started using his numbers, along with her usual lines, after his death two years ago.
Michael said: "When Susan's dad died, the morning after there was a white feather on her doorstep and she always kept it, saying, 'This is from my dad.'
"Last week there were white feathers in the garden and she thought it was because her dad knew it was her birthday but then, obviously, we won the jackpot."
Susan, who has been playing the lottery since it began, had bought a few tickets and had also won smaller prizes on three other lines.
She even plans to keep playing and bought a ticket for Wednesday's draw.
Michael and Susan said their dream was to become foster parents and the money would help them achieve this.
Susan said: "We have been wanting to do it for quite a long time and this has helped us."
The Crosslands were already in the process of moving to a bigger house to make room for their planned foster family, and they still intend to buy the same place as before.
Susan said she didn't want a mansion and wasn't sure what she would be spending her cash on.
"As long as I get blinging shoes I don't mind," she said.
