Monster Cart Upsell+Free Gifts , 553 reviews

Amazing app to increase your average order value and Conversion rate, tons of options developers have thought of everything. Hands down best upsell app on the Shopify app store. Customer service is amazing!

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

Very helpful customer service - pretty much an instant response. Haven't deployed the app fully yet, but the interface is nice and easy to use.

Great customer service and app! I had some issues getting this cart to work with my theme but support was able to get it fixed. In cart upsells are handled much better than other apps I've tested. You can even select the variation and swipe through pictures from within the cart. Very excited to see the results!

Great application that works like a charm. Everything that Shopify was missing. The customer support is also amazing, I recommend.

We've been researching cart add-ons and upselling features for quite some time. We've looked at loads of different companies, apps, etc. and hadn't pulled the trigger on any in our multi-month research. However, when we came across MonsterUpsell we were really excited about it. The usability, functionality, and customization is fantastic. The pricing (and it's scaling feature) is good, customer service is quick to respond, integration is simple, and the UI is easy to learn. It was important for us to not disrupt our daily operations during integration, to have a seamless transition for our cart upgrade, and for customers to feel like this was an improvement on their experience... Monster is all of those things. We've only been using a short time, but our very first order the day after implementation was directly connected to one of our cart upsell features. We can't prove if the customer was incentivized by the cart add-on or just wanted those products, but the fact that it was the first one out the gate is promising. Quick, efficient, fun and engaging, the UI/UX of Monster is great and we look forward to working with them for the foreseeable future.

Ty was great to talk with and was very helpful. Friendly, nice, and setup is done. Had some issues with our theme but is having the dev team look into it.

Really great app! Easily added more revenue to our store and took no time to set up. Customer service was quick and easy to work with also.

We have been shopping around for a decent cart option & I'm so glad we discovered monster! It was super easy to set up and when we ran into snags, Ty from the support team was able to get everything sorted out in no time. Can't wait to make lots of $$$ with this app.

Highly recommend this app to increase your revenue through upsell. I have a few features installed that work great, particularly add $X to get free shipping.
