Opus Cart Upsell Cart Drawer

I’ve had such a great experience with the Opus app, but what really impressed me the most was the amazing support team. A huge thank you to LULLA and KHANG – they immediately understood where the problem was and patiently guided me through it.

The issue turned out to be on my side (I wasn’t logged in with the correct email ), but they were so kind and patient while waiting for me to sort that out. Once I gave them access, they fixed everything super quickly.

What I loved most was the speed and ease of communication – no unnecessary formalities or endless emails. Just a respectful, friendly, and straight-to-the-point approach that made the whole process smooth and stress-free.

I honestly couldn’t be happier with the support I received – it makes me even more confident in using Opus long-term!

Amazing App & Excellent Support!

This app has been a great addition to my store — it’s easy to use and really helps improve my workflow. The support team is outstanding — they respond quickly and go above and beyond to help with any questions or setup issues. I highly recommend this app to anyone looking for reliable features and top-notch customer service!

I had really high hopes for this app! It allowed me to achieve the 2 things I wanted that I didn't find in other apps:
1) Add a 2-milestone progress bar to my cart
2) Add simple upsell / product recommendation in-cart to boost AOV.

Where it fell short for me:
-It replaces the existing Shopify cart page. This isn't necessarily bad, but it felt a little buggy in some ways -- didn't always scroll consistently and I'd see the page behind the cart page scrolling sometimes. When clicking back to "cart" from the native Shopify checkout page, it navigates to the legacy native Shopify cart page instead of Opus.

-The BIG one: Detrimentally impacted key conversion and AOV metrics. I watch my Shopify Analytics like a hawk and I noticed that the Checkout conversion rate metric was declining and my overall Conversion rate metric was gradually trending down. I had this app installed from Oct 10-Oct 31st, so I gave it 3 weeks. My checkout conversion rate fell from ~70% down to 59% over those 3 weeks and my overall conversion rate fell ~0.5%. Not apples to apples since it wasn't an actual split or A/B test, but it was enough to convince me to course correct. On top of all that, my main goal of boosting AOV with a 2nd milestone in the progress bar wasn't achieved. My AOV actually fell almost $1 over that time period. Again, not apples to apples with an actual split test, but this made it easy to pull Opus from our store. In the 4 days since swapping out, checkout conversion rate jumped 5% and but AOV has not recovered.

It's entirely possible that I didn't design my cart optimally with their app, but I did my best to keep it simple and minimal. Opus is a good idea and offers a strong feature set, however, here's a warning to test and monitor your metrics as you swap a critical function out such as a shopping cart.
