The following example shows how when a different priority is used with the same item in two promotions can affect the discount that will be applied.
Sell two Milk and one Bread and the “Milk and Bread for $5” promotion will apply.
Even though we purchase two milks, that promotion is not tripped as it is not a higher priority.
In this scenario, we will sell the same items, but because we have changed the priority of the promotion, a different discount will apply.
The discount that will apply to this sale is a difference of $0.30c.
Small change in some circumstances but will add up over time.
