Price Groups - Structure/Priorities/Relationships

About this Guide

If you create a lot of Price Groups, you may have a hard time figuring out why a customer was charged a certain price for an item. This is because Price Grops can affect each other in a number of ways.

Miva handles different Discount Modules in different ways depending on what kind of discount it provides.

In addition, Exclusions and differing Priorities each affect how discounts are calculated.

The content below will help you understand some of the behind the scenes work Miva does, when it figures discounts based on Price Groups.

Exclusion Types

There are three Exclusion types:

Note

An Item Group is a group of multiple items that are identical except for their pricing due to discounts (for example, Buy X Get 1 Free). These are grouped together and shown as a single line item in the basket.

Exclusions

If there are no exclusions, each price group is segregated into one of the three classifications and then applied based on the priority within those groups.

If there are exclusions:

Priority

Discount Price Recalculation
  • Any change to the basket to add, remove, or update an item will automatically force the price groups applied to the basket to be recalculated.
  • This cannot be prevented or changed.
  • Miva will look at all qualifying price groups and process each discount individually in the order based on pre-calc, items, baskets with groups and the highest priority from within each group.
  • Basket Subtotal used for qualifications is updated as each price group is applied.
