BOGO (any item): Using this function, the lowest priced menu item will be discounted when multiple items from the same Line Item are present on the receipt.
For example, a line item Burger may have multiple item IDs added to it which are 5000, 5001, 5002, 5003. A receipt comes in and has Burger A(5001) for $12 and Burger B(5003) for $8.
Burger A|1|12|M|5001 $12.00
Burger B|1|10|M|5003 $8.00
In this case, Burger B will be discounted and the discount amount will be $8.
