I am trying to find a solution to allow merchandizers to restrict a Promotion for one or many Customer Groups.
I was initially planning to create Visitor Groups for each Customer Group, and personalize the promotion based on Visitor Groups, but I've recently realized that the Visitor Groups will not work if the customer didn't Allow Cookies (or "Do not track" is enabled). Therefore, I'm reaching out to see if anyone here has customized the Promotion engine to allow the merchandisers to select one or many Customer Groups when setting up a promotion (Campaign), or if you have found other workarounds?
What is the context of your Customer Groups?
Since you're mentioning Visitor Groups, I assume its something that is decided in real time.
Our customers are synced from an ERP system with a specific Customer Group (ex: "Platinum", "Standard", etc... ). We have different pricing per Customer Group. We want to be able to personalize promotions per Customer Groups as well.
You could implement a custom promotion in code and extend an existing Promotion. Then write your Customer Group logic in the Evaluate method.
