Becoming instant millionaires usually means fast cars, expensive toys and big holidays.
This couple had other ideas though, the Daily Mail reports.
Graham and Amanda Nield said winning $12 million in the lottery was a "headache" and still buy from the markets and charity shops.
"I can’t change my habits. My friend took me to Harvey Nichols in Leeds and I nearly passed out at the prices," Mrs Nield said.
They won't even splurge for Christmas, sticking to their $100 limit on gifts.
Despite the big winnings, the newly-married couple wed at a registry office with Mrs Nield borrowing a dress from a friend.
"It is a headache. We have a solicitor and a financial adviser but the money is just sitting in the bank," Mr Nield said.
The couple did splurge on somethings though, buying houses for their five children from previous relationships.
