Opus Cart Upsell Cart Drawer

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.

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.

I highly recommend Opus Cart Upsell! It has truly taken my online business to the next level. The integration is seamless, and the features are exactly what I needed for effective upselling. What really impressed me is how it has increased my average order value without requiring any extra advertising. The tool offers personalized recommendations that fit perfectly with my products.

A big thank you goes to Katie and Lulla, who were incredibly helpful throughout the entire process. Both were always available to answer my questions, and they gave me valuable tips on optimizing my upsell strategy. Their dedication and expertise made it so much easier for me to fully leverage the potential of Opus Cart.

With Katie and Lulla's support, I always felt well-guided and informed. They ensured the entire process ran smoothly, and I was able to start seeing the benefits of the upsell system right away.

I am more than satisfied and look forward to continuing to work with Opus Cart!

Honestly, even as a free app it was worth it. More than better than the other paid cart drawer apps I've used with way more free features. But recently, I upgraded to their advanced plan and the number of features that increased AOV and conversion was brilliant. For a price that most cart apps charge double or even triple for.

I normally don't write reviews but I had a request of an amended feature within the app and the service I received was above and beyond what I expected. Lulla was attentive to my request and asked the right questions to understand what I wanted and David, the Dev charged with assisting this request handled it perfectly.

the entire exchange was seamless and I came out with not just features that are more than worth the monthly price but also a custom experience.

thank you very much to the opus team!

I was just trying the free version to enable some upselling items directly in the cart drawer. And it works perfectly!

I had to change the app for my product optoins though, because mine (as most of available product options apps) was not compatible with Opus, leading to problems during checkout. I'm using the Avis Product Options App now, and this works perfectly together with Opus). Also, if you want to track the analytics to know how many upsells this app generates from your cart drawer, you have to accept that there is a property added to your upsold products that gets displayed on the customer order confirmation notification (email) etc. that looks like this: "__cd_opus_UpSell: xxxxxxx". Apparently, they can remove it for you, but then there is no way to track the number of upsells on the App's dashboard, which would be bad too. This is important to know and to inform yourself about beforehand.

Other than that, the support from the team, especially from LULLA during my European evening time, was an outstanding experience, really. I never experienced a customer success agent as motivated like her. I'm still amazed by her way to help me: She was not only reacting instantly, guiding me through some special settings that I overlooked at a first glance, but she also checked my shop's frontend on her own and came up with some great ideas for CSS coding to match the Opus Upsell Cart Drawer's look & feel with the rest of my shop (e.g., making the button's corners rounded, and applying the same font family as I have in my shop).

The crazy thing about it: I did not even ask for it! LULLA simply noticed this room for improvement on the fly, and she suggested to apply the needed CSS code. When I gladly accepted this idea, she implemented it within a single minute.

Overall, a fantastic service and very useful app - highly recommended!
