spree_order_total_discount adds a promotion calculator that takes a percentage off the
true order total — the amount a customer actually pays, including option fees and
other line-item adjustments.
Spree's built-in FlatPercentItemTotal calculates against item_total, which is the sum
of line item prices before adjustments. If your store adds option fees on top of a
variant's price, a "10% off" promotion built on the stock calculator quietly discounts
less than customers expect.
Spree::Calculator::FlatPercentOrderTotal calculates against the order total instead, so
the discount matches what the customer sees.
Spree::Calculator::FlatPercentOrderTotal— percentage discount on the real order total- Selectable from the Spree admin like any other promotion calculator
Add this line to your application's Gemfile:
gem 'spree_order_total_discount'Then run:
bundle installCreate a promotion in the Spree admin, add the action Create adjustment, and choose Flat percent (order total) as the calculator. Set the percentage as usual.
