Decent app, but picked up that they are duplicating their charges every month. They charge a monthly fee + usage & a monthly fee again. I reached out to their support 2 weeks ago and keep getting a general response that they've passed on the message to the team leader, but still no response. Can you please refund and fix your charges ASAP? Check your charges on your monthly bill!

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

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.

Outstanding customer service! They were incredibly helpful, fast, and made sure every issue was resolved immediately. So impressed!

They charege based on ALL your orders in your store - doesent matter if the conversations are made throughou their app.

Great experience with the support team. Highly recommend this plugin for any Shopify store trying to experiment with different discount structures.

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 needed some assistance setting up my BFCM Cart, and Live Chat Support came on in seconds and helped me in seconds. Top notch... thank you so much!

Angelica Rocks! Helped me like instantly when I couldn't get my cart working. Had a problem for months. Goat.
