What merchants think

Feedback submitted

Merchants appreciate this app for boosting Average Order Value (AOV) and conversion rates by encouraging customers to add more items to their carts. It's praised for its easy integration with Shopify themes, simple setup, and customizable design. Many reported a significant rise in e-commerce revenue, with some attributing up to 20% of their income to it. The customer support, particularly a representative named Charlene, is often commended for their swift, effective, and friendly service. Their proactive approach to problem-solving is also valued.

Charlene was perfect ! This girl is funny and helpful, just keep going on with her!

charlene is the best! She helped me a lot to solve my problem and I have to say I even asked her if I could get her number so that I could contact support at any time, or rather, to be able to use YOUR support, because it was just perfect! She wrote to me at a time when I had tried everything and almost thought it was no longer possible, but then Charlene came and clarified everything briefly, she is very cheerful as I can see from our conversation. I think she is a good member maybe even the best! You should promote her ha ha. Charlene keep it up HURRA! I installed the app recently and got a good impression right away thanks to Charlene I think if the support wasn't as polite and nice as Charlene was I wouldn't be as good at communicating with this app! But as it happened, I intend to continue using this app!

I've used the app for about a week now and it definitely works! Our AOVs have been higher as customers add more to their carts to get multiple free gifts with purchase. Very happy we switched to this app for our upsells!
So far so good! Just installed the app after researching all the other cart upsell options in the app store, as well as trying a few of the other options in the past. I'm amazed at how quick it was to set up.

I have a theme with a mini-cart that isn't in the Shopify theme store and was worried about how the app would work with my theme. Charlene answered me in the chat box right away and made the updates and fixes in less than 5 minutes. I'm looking forward to seeing how this app works to improve our sales and aov!

Had the most amazing experience with MonsterApps! Recommended from my e-commerce business group.

Started off with a super helpful query from Shada late at night then followed up with super helpful Charlene the next day.

YouTube tutorials are easy to follow to get started and Charlene was incredible helping me navigate any questions I had. Incredible support and I was able to keep the chat open whilst I set up the app, able to check in whenever I needed without having to close the chat.

Obviously a business who has their stuff together and I look forward to recommending them to others.

Only took a few minutes to get the app up and running. Super intuitive, very customizable and exactly what I was looking for. Had one minor checkout thing I needed support for and Charlene was really quick about getting back to me and fixed it right away. Thank you!

I do not usually bother leaving reviews for plug-ins but this app has been the best experience for us on so many levels. Our store pretty much instantly started selling higher AOV and our CR even went up which is a huge win for us. The support team are genuinely next level on how fast they reply to things, and they even got a developer on our site to fix something at lightning speed. I love everything about this app and how easy it is and I wish I found it sooner. Thanks!

Just got the app, but because the customer service is so good I have to leave a review. Seriously. I set a campaign up easily with no tutorial, so its easy to use. I had a small issue, maybe because of my theme, but either way I contacted them. Within literaly a few hours, they went in and fixed the issue for me.

This type of customer service is hard to come by these days. Shout out to Shada and Reneen and of course the team!

This is the upsell cart app I have been looking for! 5 Stars! I tried other upsell apps but none let me run multiple promotions in cart with Free Shipping & Gift With Purchase like Monster Upsell. So great being able to incentivise customers to keep spending more for additional rewards. Fully customisable and the customer service team went above and beyond to help get me set up. Highly recommend if you are looking to increase AOV and conversion with promotions.

Great app for upselling! works wonders! We have been looking for an app that can upsell in a cart that also looks beautiful. There are lots of options out there but this app has a free plan, super user friendly and has a great design.

Thanks for the review :) .. just giving you a heads up. The FREE option is for partner stores only. The base pricing is $12.99. Great thing is you normally recover this with a couple of upsells. We also have a free trial for 10 days. :)

I had this app downloaded for a loooong time, finally took the time to set it up and I WIIISSSSHHHH I set it up sooner as it is unreal! It is soooo fast and quick, probably the fastest smoothest app i have worked with and genuinely makes our store look like its had 10x the amount spent building it. Huge shoutout to "Charlene" in particularly who has helped me more than any other support from another app. Should out to other team members and the dev there too as all have been great, "Shada" also has helped me many nights so bg shout out to her. Overall amazing i think i have asked "Charlene" a million questions and every time she has been hugely enthusiastic to help! 10/10 100% recommend!
