Samir Mazahem purchased a lottery ticket online for a dollar, using family members' birthdays as his numbers.
However, he forgot to save the numbers as his favorites, so he bought a second $1 ticket in the June 9 Mega Millions drawing.
Once I figured out, I had bought two tickets with identical numbers, I was a little bummed but didn't think much about it. Samir Mazahem
But according to CNN, the Michigan man's minor error had a major payoff, when he recently logged into the lottery app to find that he had two $1 million prizes pending.
Mazahem's plans for his winnings? The sensible 56-year-old plans to buy a house...and save the rest.
