Shopify shows each discount's combination settings one at a time. Stacklens maps every pair of live discounts, including codes against the store wide sale that is running: which ones stack, which clash so only one applies, and which are silently left out because only one side allows the combination. It flags never discount products that a discount still reaches and codes with no end date or limit, and can send Slack alerts when a new discount creates a conflict. Read only.
