Appendix C Price Calculation Algorithms
This appendix describes how price calculations are performed.
A price is calculated for every item scanned during a shopping trip. Each item has an associated
pricing method. The following item characteristics are used to determine how to calculate its
price.
• Pricing methodThe pricing method helps to determine the equation used to calculate the
price of an item.
• Mix and match numberThe mix and match number is used to indicate whether or not an
item can be part of a pricing deal that includes other items.
• DepartmentThe department helps to determine which mix and match pricing deal to apply
to an item.
The following item characteristics are used as inputs to price calculation equations.
• Deal quantity / Deal weightA deal quantity must never be negative. A deal quantity of
zero is treated as a one.
• Deal priceThe meaning of the deal price associated with an item depends on the pricing
method associated with that item. A deal price is always equal to or greater than zero.
• Unit priceThe unit price helps to determine which mix and match pricing deal to apply to
an item. The unit price is always equal to or greater than zero.
C.1 Pricing Methods
The following pricing methods are used by the PSS system:
• Split Package Pricing
• Unit Pricing
• Base Plus One Pricing
• Group Threshold Pricing
• Group Adjusted Pricing
• Unit Adjusted Pricing
Below is a description of each of the pricing methods used on the PSS system. Included in each
description is an example calculation. All pricing methods described as a group pricing method
require a price rounding method. All calculated prices in the examples are always rounded up.
