The app works fine but there's alot of grocery items that will say they are out of stock for online ordering, yet when I go into the store within the same hour of trying to order it online there's plenty of the item stocked on the shelf! What's up with that? You charge so much for Walmart plus only to limit the items we can order? AND there's a $35 minimum order for pickup?! Whats the point of paying for the Walmart plus membership...are their any actual benefits of having it?
