Opus Cart Upsell Cart Drawer

This is a great little app. I'm still learning some of the features but it mostly does what I need it to do. Upsell, discount codes, tiered rewards based on different criteria. Customizable cart look and feel. Plus so far the support has been great. I worked with Lulla to get answers to my questions and get updated to the latest version. Thank a bunch!

The freedom to customize if better than any of the other cart apps I've tried. I had an excellent experience with Opus Carts support team.

Very quick to respond, (faster than another popular app I was previously using) they helped me fix my exact problem, quickly making sure it's exactly how I wanted it.

Best cart app I've tested.

A Must-Have for Smart Upselling and Stellar Support

I’m generally not inclined to use external apps for my store, but Opus completely changed my mind. The cart is beautifully designed and packed with intelligent upsell features that truly enhance the customer experience. What impressed me even more was the exceptional support provided by Lulla and Katie—quick, responsive, and genuinely helpful. If you're looking for an upsell solution backed by a team that actually cares, I’d 100% recommend going with Opus.

Outstanding Support – Huge Thanks to Katie & Lulla!

The app itself is super intuitive and does exactly what it promises — but what really stood out to me today was the exceptional support. I had a few custom implementation questions and both Katie and Lulla went above and beyond to help. They were fast, knowledgeable, and genuinely cared about solving my issue — not just giving a generic answer.

It’s rare to find support this good, and they made the entire experience smooth and stress-free. Massive shoutout to Katie & Lulla — you two are rockstars!

Highly recommended — both the app and the amazing team behind it.

Amazing support & fast resolution
I had an issue with the cart drawer freezing on my site, and the Opus team fixed it quickly and professionally. The support was super responsive, and they kept me updated throughout the process. Really impressed, highly recommend this app and their team!
