Michele Bartlett of St. Catharines plans to buy a Jeep after winning big with Instant Chrome.
She says she continued buying tickets after she kept winning small amounts of cash.
Bartlett says she was at the store when she heard she won.
"I saw Big Winner and thought I won $1,000 at first. I was shocked when I discovered it was $100,000!"
She says she also plans to save some cash for her retirement and share some with her son.
The winning ticket was purchased at Avondale on St. Paul Street in St. Catharines.
