Your customer just paid. It is the best moment to sell one more item. Combo shows a 1-click post purchase upsell on the thank you step. No card details again, the product joins the same order. If they say no, show a downsell. Before checkout, a slide-out cart drawer with a free shipping bar and an add-to-cart popup suggests the right product. Target offers by product, collection or cart value, A/B test them, and see revenue counted only from real orders. One app instead of two.
