(CNN) -- Someone in Maryland is about to have a wildly euphoric weekend.

How to pick a number for Mega Millions Sales skyrocketed at Manhattan Tobacco, a New York convenience store, cashier Alex Shanahe said. He said the store has proved to be lucky before, having sold winning tickets of $3 million and $5 million.

Myra Langford, 70, a retired school administrator, said she knows the odds but still bought five tickets.
If she wins, Langford said, she will help fix the roof of her church and move out of the cramped Queens apartment she lived in for the past 47 years.

Economist Austan Goolsbee, a professor at the University of Chicago who also chaired the White House Council of Economic Advisers, said the winner or winners should take the lump sum instead of the annuity.
The choice comes down to interest rates, and with interest rates at zero, the lump sum just makes better financial sense, he said.
"If you are fortunate enough to win the lottery, you most certainly want to take the lump sum," Goolsbee said.
Psychologist Scott Bea said if a winner is a poor money manager and has been unhappy in life before winning, that's likely to continue.
"It solves one problem, but it creates a half-billion others," he said. "You have about no chance at winning this, but it really gets people excited."
His wife asked him if the couple could spend $10 on lottery tickets.
"We could probably flush it down the toilet and have the same outcome, but if it gives you some hope, why not?" Bea said.
