Upcart—Cart Drawer Cart Upsell

UpCart delivers the exact functionality I was looking for...it displays recommended add-ons as in cart upsell offer. The product has more features than this, but this is the use case I was looking for. I hit a roadblock with configuring nested Buy X Get Y discounts and having them show up in the cart. This is not a limitation of UpCart, but a limitation of my Shopify knowledge and/or a real limitation of Shopify functionality. Patti from UpCart spent a significant amount of time helping me troubleshoot the issue - she even went so far as to record and share a step by step video showing me her suggested resolution. I'm beyond impressed!
