No Product, 2 Orders & Wrong Pricing

No product listed, such as Eskort frozen pork sausages, a common SA product. When looking at products, specifically their Antigua branded coffee as an example, it appears at one price on the app and a TOTALLY different price at the store. When ordering various products, it sometimes makes a seperate order for a different time, but I know the store/s in my area DO have that product, which creates another order with another minimum order value and another delivery fee. I try to order only when absolutely necessary, never ever otherwise.
