@nathan.perdriau: Five rules for in-cart upsells that most brands get wrong. 1. One offer per slot. Multiple offers create decision fatigue and kill take rates. 2. Relevancy over price. A strong discount on an irrelevant SKU gets ignored full stop. 3. Push high margin SKUs. An incremental $4 in gross profit is not worth the slot. 4. Keep the offer simple. You have two to three seconds of legibility before they move on. Complexity works on the front end. Not here. 5. Measure by gross margin lift, not AOV. AOV will steer you toward low margin SKUs every time. The metric you optimise to determines the outcome you get.
