The app is amazing, and the customer support is top-notch! Big thanks to Katie and Dev Mia for the quick help!

We've had an amazing experience with Opus. Their support team (Vivian) is always responsive and goes above and beyond to assist us. The features they offer are user-friendly, making our workflow seamless. Highly recommend them for anyone looking for reliability and excellence!

This is by far the best cart upsell plugin we've used. After using another cart-upsell plugin (MC), we had no support and the cart was giving away way too much for free. Allowing our customers to get free gifts, plus use coupons and we got told there was no way to fix it. We paid around $20 AUD per month for the plugin, but we decided to give Opus a go and WOW, it's free and the support from Vivian has been nothing short of amazing. Vivian has been so attentive and follows up to see how we went with implementing some work-around ideas she had so we can make Opus work for the gifting system we have. Nothing was too difficult and instead of saying "our app won't do that" she found alternative solutions for us. Our cart upsell now works perfectly and we couldn't be more happy. Thank you Vivian for your help - you're an asset to Opus :) and thanks to Opus for creating a great, user-friendly app

Great app and even greater customer service! In 30 min I had 4 custom changes made - How great is that?!

The customer service responds fast and they have helped me make adittional changes. This has to be on top of my favorite apps for shopify. Thank you so much Lulla, Mia and the rest of the team

VIVIAN, LULLA and dev DAVID have been amazing in helping me add functions that are not standard on the opus cart and help integrate their app with other third party apps to work seemlessly! I would 1000% recommend this app just for the support that I've received alone. The app is also good, but Vivian, Lulla, and David really helped me so I don't have to keep looking for a slide cart that can work with our already functioning website.

This app is awesome at increasing average order value! The upsell and cross-sell features are incredibly effective, and the customizable slide-out cart makes for a seamless shopping experience. On top of that, the support team is outstanding—Katie went above and beyond to assist us.

The support is amazing and I could get attention in each detail. Lulla from support team has help me with my question
