Can I exclude sale items from discount codes?

Question

I'm running an e-commerce store and want to maintain control over my discount strategy by preventing discounts on already marked-down or sale items. I've noticed that some customers try to stack discounts, which can significantly reduce my profit margins. I need a clear method to exclude sale items from additional promotional codes while still offering attractive deals to my customers. What are the best practices and technical approaches to implementing this restriction?

Discount Campaign Break-Even AnalysisEvery discount campaign has a break-even point - the number of incremental conversions needed before the campaign becomes profitable. Running campaigns below break-even is subsidizing purchases you would have gotten anyway.Break-Even FormulaTotal Campaign Cost = (Total Redemptions x Discount Amount) + Campaign Delivery CostIncremental Revenue Needed = Total Campaign Cost / Gross Margin %Break-Even Orders = Incremental Revenue Needed / Average Order ValueExample: 500 redemptions x $15 discount + $100 delivery = $7,600 costAt 40% GM: Need $19,000 incremental revenue = ~190 incremental ordersBreak-Even by Discount LevelDiscountIncremental Orders NeededFeasibility10% off on $80 AOV, 40% GM33 incremental per 100 redemptionsFeasible with good targeting20% off on $80 AOV, 40% GM67 incremental per 100 redemptionsRequires precise targeting30% off on $80 AOV, 40% GMExceeds GM - always loses moneyAvoid at 40% marginGrowth Suite: Purchase Intent Prediction maximizes incremental order percentage by targeting only walk-away customers - ensuring a higher proportion of redemptions are truly incremental, not cannibalized full-price orders.
