KFC Charging extra for each individual item for Delivery on KFC App.

KFC States that their delivery is free (Which it is) on the KFC App, however upon closer inspection you notice that the prices of each item has gone up by between R10 and R15 for delivery compared to the prices of the same items for Collection. What nonsense is this KFC? And not everyone is aware of this. You expect us to pay more for delivery and then claim your delivery is free but there are hidden costs in your individual prices. Do better. We want to use the KFC so that we avoid paying exorbitant prices such as when using other delivery services. But it looks like I will have to stay away from KFC altogether because of this.
