Monster Cart Upsell+ Free Gift

love working with monster! theyre the best and have a super responsive CS team!

Incredible support from the Monster Upsell team. They go above and beyond to customise our cart and ensure we are happy with the overall features and functions.

Great, easy to use app for upsells. We use the functionality to offer free gifts when customers hit a certain order threshold. When I run into issues, the customer support team is swift to answer and action. 5 stars!

WHAT AN APP! So useful and you can instantly see the benefits from an upselling perspective. What is so great is that the team are constantly upgrading and thinking of new methods and ideas to boost your revenue on the cart. The customer support is truly exceptional, even getting replies to chats on Sunday and the team are also open to implementing ideas if good, so one of ours is even on the roadmap thanks to the founder agreeing it is good. Wish all Apps had such great service in addition to a top product! HIGHLY RECOMMENDED!

Terrible app. I was a client for quite a while and wish I had tapped out sooner. We experienced multiple bugs and glitches that the team repeatedly approached with bandaid fixes, only for the same problems to return soon after. These issues ended up costing us a significant amount in lost sales, as many of them directly affected the cart, including items duplicating in quantity or the cart freezing. We also found that these issues were causing our ATC events to be overcounted, which had a significant impact on the data being carried over to our advertising platforms. The last straw was when the issue happened AGAIN, except this time the cart quantity was not only duplicating, but tripling after selecting ATC just once across our products. We had a sale running at the time, and customer service told us we would need to wait 12–24 hours for their devs to "look into it". We simply could not afford to wait that long, especially when this same issue had already returned multiple times. By the time they got back to me, I had already switched over to a much more reliable cart app. Their proposed fix was that they now had a new V2 version of the app and recommended that I install that instead. Fantastic. That was the solution after the bug had already returned multiple times and impacted our conversions for who knows how long. We also received complaints directly from customers about issues with the cart, so this feedback was not isolated to what we were seeing internally. What further confirmed the issue for us was that only a few days after switching cart apps, our ATC rate normalised despite similar traffic volume, and our conversion rate improved significantly. We are a 7-figure brand, and I am confident in saying that we potentially lost thousands of dollars in sales from the same issue occurring without us even knowing. I am just glad our customers were there to point out the cart issues when they happened. Terrible app. I was a client for over a year and wish I had tapped out sooner.

This app sounded affordable at first, but the issues it caused ultimately cost us far more than we ever saved by using it.
