Pick n pay online app is purely bull****

1st and last time I'll use this online app for pick n pay. Don't implement something that doesn't work! This app doesn't show what items are out of stock which creates an even greater dely of my order to be delivered. I ordered 14:45 and the apo shows I'll only be receiving my order 18:00 - 19:00 Ridiculous! What an awful experience.
