unfortunately support is ghosting me and is not answering to any of my tickets. App stopped working and 20% of orders are not discounted.

Ty here one of the founders. Please respond to the emails we have been sending. I can see the team has been trying to help but aren’t getting responses.

MonsterCart is a really great app! We've tried a fair few similar apps, but have always come back to MonsterCart as the interface is easy yet powerful to use! The customer service is above & beyond, super helpful.

Warning this does NOT work with product variants. It also does not work with subscription products (i.e., excluding subs from upsells) Their product says "fully compatible with product variants" but that does not mean it's possible to do a product upsell with a specific variant. Instead it means that it can apply in the same way to all variants of a product.

I couldn’t be more impressed with the support I received from Charlene at Monster Upsell. From the moment I reached out, she was exceptionally helpful, patient, and knowledgeable. She took the time to fully understand the issue, explained solutions clearly, and went above and beyond to make sure everything was working perfectly. Her communication was fast, friendly, and professional throughout the entire process. It’s rare to find customer support that truly cares, and Charlene absolutely delivered that. Thanks to her outstanding assistance, the entire experience was stress-free, and our store is now running better than ever. Charlene is an incredible asset to the Monster Upsell team, and I’m extremely grateful for her help! Highly recommended support — 10/10!

I'm not the best with IT so needed a bit of guidance and was so well looked after by Angelica who helped me through the set up stage. All working well now. Her help and patience was much appreciated. Thankyou

I had a play with over 10 different upsell+free gift apps, and Monster Cart came out the winner, offering everything I needed, easy customisation and fair pricing. The cherry on top, their customer support is next level. Highly recommend this app. Thanks, Monster Cart Team!

Amazing customer service — Charlene has been super helpful! Love how flexible the customisation is across different cart types. We had a few hiccups with integration, but the dev team helped us sort it out quickly.

I dont write reviews very often, but i had to give feedback from what has been a great experience all round with this app. Not only does it give me a lot more sales and easy to use - but the customer service is the best ive ever encountered. I'd recommend this app to anyone.
