This cart recommendation app has been very effective for our store. A special thanks to Katie for her patient and helpful support during setup—she made the integration process smooth and stress-free.

Just started using the app and love the customization! I've used other Upsell cart drawers and this interface is more friendly, more customizable, and the service is top notch! Thanks Lulla, Vivian, and Mia - you're amazing!!!

Opus cart upsell is good. Its has many options to help suit it to your needs. The Opus team also helps you with modifications. The pricing is reasonable as well. The only drawback is the analytics sometimes aren't tracked well.

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.

This is hands down the best app out there! The support is absolutely outstanding – no matter when you reach out, someone is always there to help, and they truly go above and beyond to make sure you're satisfied. I'm deeply grateful to Lulla, Vivian, and the entire dev team. You're doing an amazing job – thank you for being there!

The issue was resolved quickly. The customer support replies were fast and polite. Thank you, Vivian, for your great service! The app is easy to use and has all the features I need.

Application super pratique et support au top, très réactif et à l'écoute des demandes, je recommande à 200% cette application !

Stop scrolling and install this app! There’s the best support with in-depth understanding of Shopify coding, quality people with personality and style and too many amazing options YOUR STORE NEEDS!

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.

Great app, Lulla kindly helped me by explaining how to correctly configure a specific function I was needing

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!

Support is so quick to respond. Lulla & Mia have been amazing in helping to get the app setup and tweak a few features so we can use it for our store. The cart is clean and has features others don't.

Superbe app, les fonctions timer, upsell et l'affichage des badges sécurisés sont des vrais plus. Merci à Lulla pour l'aide pendant la configuration.

Thanks to Lulla and David – really good customer support! I had an issue with my cart not working properly, but the Opus team – especially Lulla and David – fixed it incredibly fast. Their support was efficient, friendly, and made me feel truly taken care of. Great experience overall!

I had an amazing experience with the support team! They were incredibly helpful and quickly addressed all of my concerns. The layout issue in my cart was fixed promptly, and now everything looks perfect. I’m really happy with the service. Highly recommend!!!

The app is super intuitive and easy to manage. The support is also one in a million. Asked Vivian for help with a checkout issue and the dev team helped me, thank you guys!!

Great customer service! The team is responsive, helpful, and really cares about merchants. Highly recommend this app!

Just wanted to drop a quick review because I’m honestly loving the flexibility your app gives for customizing the cart experience Makes a huge difference for us! Special shoutout to LULLA and DAVID for the amazing support – super helpful and quick! Keep it up, can’t wait to see what’s next!

Great service from Katie. Love Opus Cart so much! I use for all my clients now after switching from MC

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!
