What drives those sales from lottery winners
Harold Côté, who owns three Sobeys-affiliated c-stores and gas stations—two Petro-Canada and one Shell—in Sherbrooke, Que., says he too witnessed positive impacts from the sale of a $1-million winning Québec Max lottery ticket at his Shell store in April, 2023.
“It was in the news here and right away we got an increase in traffic and lottery sales went up at that store,” said Côté.
But he said the bump in business was ephemeral.
“It only lasted for a month or so,” said Côté. “After that, things pretty much went back to normal.”
Still, he said the in-store sign from Loto-Québec attesting to the sale of the million-dollar lottery ticket is a fun and constant reminder that Lady Luck smiled on one his customers at that location. “It makes it more tangible than seeing someone it on TV,” said Côté. “It can happen to someone here.”
For Luke Clark, a professor of psychology at the University of British Columbia (UBC) and director of UBC’s Centre for Gambling Research, the uptick in business at c-stores that sell big-win lottery tickets is both a result and a reflection of cognitive distortions that arise when people gamble.
“People over-estimate their chances of winning, their ability to predict outcomes and their degree of control over chance events,” said Clark. “Lottery games pair a low price to play against an extremely low probability of a very large jackpot prize, and this combination seems to bring out faulty patterns of thinking.”
Clark pointed to a 2008 study by the American Economic Association that analyzed the weekly sales of three lotto game tickets at more than 24,000 store-level retailers in Texas between Jan. 2000 and June 2022.
Dubbed ‘Gambling at Lucky Stores: Empirical Evidence from State Lottery Sales,’ the study found that ticket sales at stores that sold winning tickets of between $10,000 and $51 million, depending on the game, experienced a 12% to 38% increase in ticket sales.
“We find that the effect dissipates over time but that sales at stores that sell winning tickets remain elevated for up to 40 weeks, conditional on contemporaneous sales,” the researchers said.
They said the effect increases with the size of jackpots and is larger among people with lower incomes. In addition to advertisements about big wins, the researchers believed higher store sales resulted from “what we call the lucky store effect, whereby consumers erroneously increase their estimate of the probability a ticket bought from the winning store itself will be a winner.”
Clark said that those findings jive with the known tendency for people who are confronted with uncertainty, like in a lottery, to look for ways to increase their control over the situation.
“People like to choose numbers that are special to them, such as family birthdays, even if the lottery offers a random ‘quick pick’ option that would offer the same odds of winning,” said Clark. “I see the lucky store as a more extreme version of this bias, as if the store itself has been imbued with some magical properties. The player might drive miles out of their way to acquire some of that luck.”
