Incredible customer service by Charlene; I had tech issues, theme issues, customization issues, use issues and feature issues - she resolved every single one incredibly fast. From install to every customization I wanted + all the info I needed took about half an hour. 10/10 recommend.

I heard great things about this app—the first day of trying it out, looks great and robust. We aren't sure if we'll keep it, profits will tell. However, shout out to their customer service. Charlene was super helpful! We had access issues, and Charlene was just 10/10, providing instructions and being super patient. Just for the sake of customer service, I hope the app fits our goals!

Highly recommend this app for higher conversion rates. Customer service is great and I usually have a response for any queries within minutes. Definitely recommend if you like a place for your cart upsells and campaigns to be all-in-one.

THIS APP IS FABULOUS!!! I tried a half dozen different free gift/upsell apps and none of them worked the way I needed, plus they were clunky and un-polished. This one does EXACTLY what I need in terms of handling Shopify discounts, allowing selection of free gifts, etc. And it knows to check whether people apply discounts or remove items so that the cart value falls below the free gift threshold.

And I love that just about every element of the UI can be customized easily without css. Super useful. Fonts, colors, outlines, corner rounding, text, etc. can all be changed through the UI; and most elements can be easily hidden too.

Finally, the customer support was fabulous, fast, and knowledgeable. They jumped right in to help me figure out the source of my problem - and were able to quickly identify the issue stemmed from a font incompatibility with my theme.

I've tested the app on all the major browsers and all work fine as far as I can tell so far.

Overall, two thumbs up and 5 stars for Monster Cart Upsell!

Worst support we've received from any app provider over the past five years we've been on Shopify. The app was breaking our 'Add to Cart' button so that when it was clicked, nothing would happen. It would take quite a few clicks at times to add an item to the cart, and even then our old cart would load, not the MonsterUpsell version.

I sent a screen sharing video to support regarding the issue, and they said they'd get back to me in 24-48 hours. 48 hours past, so I followed up to see what the status was.

Here's the response I received, "Our dev team and even the head dev already checked the issue and tried their best to make our app work in your store. But unfortunately, we can't support your theme and therefore we can't do anything from our end."

Disappointing for sure, but I was understanding, until I went to uninstall the app, and saw that the dev team chose to leave the app enabled on our LIVE theme when they knew it was breaking our 'Add to Cart' button.

First of all, they should have been testing the app on a backup theme that was not published/live, and second of all, they should have immediately disabled the app once they confirmed they couldn't fix the issue. That's just basic, developer 101 type of stuff.

It just shows how little they care about their customers. I'll be finding another in-cart upsell app, and I recommend you do the same.

Ty here one of the founders... 🥲🥲 Store owners are the heart of our business and the team works hard to support as best they can... (see past reviews)
Trust me - it kills us to hear this kind of feedback. 😅

Yes totallllllyyy agree... Testing on backup themes is our normal standard operating procedure. I'll be chasing down how and why this situation played out.

As for compatibility...
Unfortunately yes... your theme clashes with the loading of our app. This is a rare situation. We had our main devs on it for 2 days straight and couldn't solve it.
Sorry - wish I had a better answer here. 🥲🥲
