I'am developing some custom promotions.
Does anyone have a nice example of an expression xml (edited by the Expression Editor.exe) to help me understanding it?
you can find those where you ecommerce framework is installed e.g. \eCommerceFramework\5.2\Shared\Apps\Marketing\Promotions\Configs\BuyXGetOffDiscount.config
Copy the contents from that file and paste it in Expression Editor.
