Ego Cart Drawer Cart Upsell

Tried 5 different cart upsell apps and this one has the most customizable features, the price is also very fair. When I had a question support agent Lulla was very helpful and resolved it immediately. Thanks a lot!

Guys, it's my 3rd time using OPUS for 3 of my clients and they have a reason why they are so highly rated. Legit they make magic. Lulla is the person that made all these work! Thank you so much!

Opus Cart Upsell has been a game changer for my store, but what truly blew me away was the support team behind it. Vivian, Lulla, and their developer, Mia went so far above and beyond with custom coding and design tweaks that I honestly couldn’t have built a better cart drawer even if I could snap my fingers and make anything appear. They jumped on every request, helped me match my brand perfectly, and turned all my ‘it would be amazing if…’ ideas into reality. If you care about having a high‑converting, beautifully designed cart drawer and a team that actually listens and builds with you, this is the app. And Vivian, Lulla, and Mia are the reason I’m leaving a 5‑star review.

good support

I recently experienced an issue where discounts were not showing correctly in the cart when adding bulk products from my custom-built page. Even though it happened right before Black Friday — one of the busiest times of the year — the Opus Cart support team responded incredibly fast and resolved the problem quickly. I’m genuinely impressed with their efficiency, professionalism, and willingness to help, even under pressure. Excellent support — highly recommended!

Vivian was a fantastic support setting the store up with me.

I’m really impressed with the Opus Cart Drawer & Cart Upsell app! It’s simple, clean, and super easy to use—perfect for my small business. The features work exactly as I need without any unnecessary complexity. What truly stood out was the support. Vivian and the developer David helped me out on a Saturday evening, which is absolutely exceptional customer service. They quickly understood what I needed and solved everything with patience and professionalism. Thanks again guys!
