The most recent lucky store winner bought his ticket last week and won £100,000.
Store employees said the winner was a regular customer who visits the store twice a day and always uses his own numbers.
Little Grocery store employee Debbi Inman said every time the store sells a winning ticket it brings more people through the doors.
"When the pots are high a lot of people come in hoping for that big pot," Debbi said. "You want to win and this is the place to do it."
