Volume Discounts are implemented using Magento’s Shopping Cart Price Rules and their purpose is to give customers discounts based on the Subtotal of their Cart. TT11 gained significant competitive advantage using this tactic. To see currently active levels of Volume Discounts open this page and look for discount rules named “-XX% if Cart Total is equeal or greater than XXX EUR”.
Rule Setup
Every Volume Discount Rule has following settings to decide if rule applies:
- Country(ies) – originally Magento does not have it, this setting was added specifically for TT11
- Website
- Customer Group
- Priority – sets the order of rule evaluation, rules with smaller priority number are evaluated first
Using these parameters you can set-up many rules and decide how and where they would trigger.
You can read original Magento Documentation for configuring Shopping Cart Price Rules here: http://docs.magento.com/m1/ce/user_guide/marketing/price-rules-shopping-cart.html
[alert]NB! For successful rule configuration it is important to understand the concept of “priority” and the fact that some rules can stop further rule evaluation-execution when validated![/alert]
Following this principle TT11 Volume Dicount Rule that gives largest discount is evaluated first and if it does not validate, then next rule that gives lower discount is evaluated and so on, until some Volume Discount Rule validates and stops further rule evaluation using it’s setting “Stop Further Rules Processing”.
“Volume discount cannot be applied” messages on products in Cart
This is a custom functionality that was introduced to help customers understand why they are not getting a Volume Discount for product that should give them one. Volume Discount is not applied to products:
- with Special Price (discounted price)
- that have “Net Sale Product (Volume Discount do not apply)” parameter set to “Yes”
