Defined in:

app/models/spree/calculator/percent_per_item.rb

Overview

A calculator for promotions that calculates a percent-off discount for all matching products in an order. This should not be used as a shipping calculator since it would be the same thing as a flat percent off the entire order.

TODO Should be deprecated now that we have adjustments at the line item level in spree core
