Oxify Cart Drawer & Upsell

Hi there, thanks for the feedback and sorry for the frustration. This is already fully supported. The cart drawer has a built-in discount code field, and codes stack with the upsell offer - the two use separate mechanisms and don't block each other. The reason you're not seeing it: the Discount Codes module is off by default. Turn it on in the app under Cart Editor → Discount Codes, and the input + Apply button will appear in your drawer right away. One other thing to check - in Shopify Admin, open your discount code and make sure "Combines with → Automatic discounts" is ticked. Our upsell discount runs as an automatic discount, so if your code is set not to combine, Shopify will block it on its side. We also expose per-type stacking controls under Settings → Discount Settings if you ever want finer control. If it's still not showing after enabling it, reach out at [email protected] or via in-app chat and as we haven't got any request from your end, we'll get onto your store and sort it the same day.
