Ways to improve Shopify discount profitability
Limit discount depth
Use the smallest discount that still improves conversion or clears inventory.
Raise average order value
Use bundles, quantity breaks, or free shipping thresholds to protect margin.
Avoid stacking discounts
Be careful combining coupons, sales, free shipping, and paid ads.
Track repeat buyers
A lower first-order margin may be acceptable only if repeat purchase value supports it.
