I had an issue with the app and reached out to support and Lulla was an absolute pleasure to work with. She went above and beyond to see if my request could be solved and was incredibly friendly. She even offered to solve another issue I didn't think of. Looking forward to using the app and working with this support team for additional features. I can't wait to see what they'll add. Amazing all around. TY Opus Team!

I have just set up the app in my online shop and needed some support in customising my fonts. Lulla responded to me in no time and implemented my customisations super fast! I can only recommend this app to everyone and especially the people behind the support! Worth more than 5 stars for me! TOP!

A fantastic user experience. I wanted to custom code something into my cart, and these guys worked persistently for two days as there was an issue with my store, and they stuck through until we fixed it. Would 100% recommend it as it gives you full functionality and if you have any issues, their support will make sure its fixed.

The support is incredible and the app is very good. The set up is very easy and the functions are perfect

Opus has been one of the best free apps we've used for our store. It's simple, customizable,saving us from needing multiple paid apps. The customer support is outstanding fast, friendly, and highly cooperative. Huge thanks to Katie and the Opus team for making this an essential tool for us!

For a free app, the level of support is AMAZING. Vivian and Mia helped me customise the cart specifically to my liking and were super quick to respond. The core functionalities are mostly what you need, but the app definitely shines with the customer service and the customisation.

Such an amazing app with an outstanding customer support! Thank you so much Vivian and Mia! 10/10 recommend

Setup was a breeze, and the customization options let me tailor everything exactly how I wanted. But what really sets Opus apart is the support team—seriously, they are next level!

Opus Cart Upsell Review – A Game Changer for Boosting Sales! ⭐⭐⭐⭐⭐ I recently installed Opus Cart Upsell on my Shopify store, and I must say—it has exceeded my expectations! The app is incredibly easy to use and has helped me increase my average order value (AOV) significantly. The upsell and cross-sell features are well-designed, and the customization options make it easy to match the app with my store's branding. One of the best parts is how smoothly it integrates with my store without slowing it down. My customers love the seamless shopping experience. Plus, the analytics dashboard provides valuable insights into upsell performance, helping me refine my strategy. A special thanks to LULLA, who assisted me with everything I was searching for. Her support was top-notch, and she made the setup process effortless! If you're looking for an easy-to-use upsell app that delivers real results, I highly recommend Opus Cart Upsell!

Le service client est ultra-réactif et l'appli est vraiment quali. Je recommande vraiment ! Merci encore Vivian et Mia

The app is nice to use and the support team is also great! My problem was resolved in just few minutes by Vivian and Mia. The only drawback is that they don't have geo targeting as of now.

Such an amazing app. The app is so easy to use, and a lot of custimazation options to match my store! Definitely recommend

Amazing customer service. Helped me so much with my cart and editing my store directly. I’m a beginner so really was needing help and they’ve made the process so straight forward. This is a 100% real review and my cart can be found at vevaboutique.com that they helped me to create. Honestly cannot recommend this app enough! Thank you KATIE and dev MIA
