Wake Forest Police said Rebecca Downing Wilson, 58, of Youngsville, has been charged with driving under the influence and careless and reckless driving.
Police responded to the report of the car into the retail giant about 4:30 p.m. About 15 minutes later, police received a separate report that moments earlier Wilson had been involved in a hit-and-run involving another vehicle near the Rent-A-Center at 11216 Capital Blvd.
That incident remains under investigation.
Wilson suffered minor injuries and was treated at the scene.
No one else was hurt.
Walmart officials estimate the damage to the store at approximately $50,000.
A tow truck removed Wilson's car from the scene.
