Upcart—Cart Drawer Cart Upsell

Very Glitchy, Combined discounts don't work well here, yet tehy do on other apps. Also their tiered rewards don't honor their exclusions so I lost a good amount on orders that had low margin items that pushed the order to a high rewards threshold. Customer service did give me a refund for a month to help offset some of that cost. That is why 3 stars instead of 2. If you only have basic upsell needs this works, anything more than that I would go elsewhere.
