Alan, 46, and Kim Elliott, 45, from Aspley, Nottingham had bought the ticket on March 23 from the same newsagent and found out that they had made it they took several old tickets to the newsagent to be checked.
But the couple may have already lost on around 7,500 pounds (USD 11,540) in interest by not banking their ticket on time.
They said they weren't going to let that worry them and now plan to splash out on holidays and swap their Peugeot 308 for a luxury Range Rover, the Daily Mail reported.
Alan told how he thought his local newsagent was playing a trick when he checked the ticket and revealed it was a one million pounds (USD 1.5 million) winner.
