Shoprite Wierdapark Bread is the most expensive in South Africa

The staple food is Bread. But Shoprite Wierdapark are the MOST EXPENSIVE in South Africa. Whenever I go to buy Brown Bread I am told it is in the oven and I must come back at a later time. The second visit means another trip so the bread has become so expensive. Why can't Shoprite get their act together and have bread available throughout the day? Chatting to their managers has no impact. They do not advertise an email; address but would like to let them know
