Yep it's reliable it does tell you things at Walmart does sell. However it has very bad recognitions on addresses I do not recommend the pickup delivery. Instead of choosing the Walmart closest to my house chose the Walmart that was pretty much an hour to 2 hours away from my house just to pick up groceries. In the end to get from my house so that Walmart I pass by 6 to 7 Walmart so we're closer to my house. If possible please fix this app.
