Christmas came early for mum-of-two Jenn Burston after she decided to play a chance Lucky Dip online.
She matched five balls and the bonus ball on the Lotto but after checking her numbers, she thought she had won £3,000.
It was only when the 27-year-old from Exeter did a further check that she realised the festively fabulous truth.
Jenn told her local paper: "I always play Lotto online and saw the big Lotto rollover so decided to have a go. On Wednesday night, I was on my way to bed and thought I'd look at my account to see if I'd won anything.
"I logged in on my phone and it said I was a winner - my numbers were circled. I thought hang on a minute, I think I've won £3,000 and took my phone to go and show my husband.
"All my husband Ian kept saying was, 'are you sure it's your ticket?' so I tried to show him on the phone, but we were so excited and couldn't really see the amount because it was so small, so we decided to get the iPad log on with a bigger screen. "
"Once we realised it was £3 million neither of us knew what to do next - so I called my mum and my husband called his dad, and by this time, it must have been after 11 pm."
Jenn and husband Ian, who have two young children together, are planning to splash out on a bigger family house in the same area.
Jenn, who is a part-time administrator who only returned to work last month following maternity leave, added: "I keep asking myself, just how do you spend that sort of money? I'm sure with £3million in the bank the knack will come for us."
