Great app. A few bugs here and there but nothing that their team can't handle. Makes it very easy to promote products and increase average cart value. Definitely worth the cost.

An excellent app that was easy to use and turned our dead space on the slideout cart into profitable real estate very quickly.

The best support EVER. I have downloaded a lot of apps from the Shopify store, but this company provides the BEST customer support by far compared to anyone else. I dont usually write reviews, but these guys surpassed my expectations and helped sort out every minor issue I had with the app. Their developers are excellent. 5 STARS!!! Highly recommend!

Really Easy To Setup !! You can choose collections, products, rewards... anything !
Thanks for the good job and now... It's Time to SELL MORE :)

First of all, you will deal with a "legendery" friendly team. In addition to this, what a great product, "Mate!", you can combine almost three ways to upsell and it works from day one increasing my average cart size in a snap.
I spent hours looking for something (an upsell app) that fit my store (more than 100 collections and 3k products). Try it, that's all I have to say and see by yourself you won't be disappointed.

I use the app and it helped me a lot to grow my AOV, and the customer service is amazing. Thank a lot to the MonsterUpsells 'Team !

The interface is well made. Easy to set and to customize. The developpers have tought a lot about the UI and UX. What I appreciate best is their support, top notch. The app still need to improve many aspects on the upsell parts to fit most case scenarios but for our use, it is beyond expected. The dev team said they are working on their roadmap to add more features and the team seem open to more customization.

Monser Upsells is great, simple to install and use and integrates really well with the design of my site. Most importantly the user support is awesome, issues solved in minutes! 100% recommended

I installed the app, and had some questions, the support responded within minutes, and helped with all my inqueries. Its launched now, and look forward to test it on real customers. Can highly recommend :)
