The app was very agonizing. But not as agonizing as the overcharges 9 out of 10 visits, shopping! I try to catch OC before I leave the store. And if after 6pm I have been treated with rudeness+ ignorance...by store employees. My reason for this it causes many return trips to store, melted ice-cream, my time just to name a few! One store manager intercepted on an overcharge(s)what an idiot; told me to check zipcode, and then tells me to always get checked by him !! Oh, ok so how will that happen? Can I get your schedule so I can know when to come shopping oh Mr Manager. Seriously??? So people heads up check those reciepts!! I can't afford to pay these over charges, be it $1.00 up to $36.00 .it's either their computer system or human error or Both. Thanx kt
