Monster Cart Upsell+Free Gifts

Amazing app, and crazy high conversion rate compared to any other alternative I tried in the past, I will be using it for a long time now!

Very easy set up for the app. I am a complete Shopify rookie and very very easy to work through. I needed one little bit of extra assistance and Charlene was super quick to respond and sorted my issue very quickly!

Now for all my years using Shopify & plugins/apps, I have had some great service and support..... but absolutely nothing like these guys! TY, what a man!! Thank you good sir! Don't download CartBoost+.... GET THIS!!

Great app with heaps of features, that is backed by a quick support team! I would recommend it for any eCommerce store.

Great app so far. I think it will be helpful to customers. Charlene was super helpful with the setup, and quite funny as well which is a bonus.

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 !

Fantastic experience. Charlene went above and beyond. App is slick and works like a dream. Highly recommend this app and team!

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!

charlene did great work heling me with everything i need to get started

Amazing cart, does what it says on the tin. Really useful features. Super well done.

Where this app is let down, from my experience just now, is its lack of developer environments. Meaning that, if you seek changes made by the developer, they cannot preview their changes unless they activate the feature on your live theme.

For example, I enabled the Sticky Cart, which basically didn't work at all. It didn't appear at the right time in the scroll, and when it did appear, it would appear at the top of the page, blocking our navigation menu.

I sought help from their customer service, and the developer had kept the erroneous sticky cart enabled on my live theme while trying to make the fixes.

This meant that the faulty sticky cart has blocked customers from navigating our store. The developer also wasn't able to fix the issue properly, and kept the sticky cart live without checking overnight, so there was 1 night of customers who weren't able to navigate our store once reaching the product page due to the frozen sticky cart. Had a lot of drop-offs.

I had purposefully kept the sticky cart turned off, knowing it had issues, but the developer continuously turned it back on. This specific concern may not be the fault of the developer, but more of the lack of "preview" environment of this app.

Anyways, I will probably give up on the Sticky Cart and seek another app for it. I will probably get a reply that the sticky cart feature depends on theme to theme, and every theme is built differently. I get that, it's just that the correction of this wasn't handled properly.

Overall, really happy with the Main cart, but terribly disappointed in the process of getting the sticky cart to work.
