Walmart is using artificial intelligence and other methods to crack down on fraudulent sellers on its website.

While there were signs that customers were switching from more expensive items to more affordable ones, Walmart was “taking less price than its peers.”

Multiple people were involved in stopping and detaining the suspect in Saturday's attack at a Walmart store in Traverse City. One was armed with a pistol.

A Walmart employee was helping a customer check out when she heard a warning that someone in the store had a knife.
