Monster Cart Upsell+Free Gift

Feb. 21, 2026

I had a good run with this app initially, but after one issue it quickly snowballed. Last week I raised concerns about billing inconsistencies that did not match their own pricing table. The initial customer support was extremely disappointing - I received one-line replies to a detailed report and was simply sent a link to the same pricing table I was questioning. For a high-volume store paying around $90 per month, I expected more serious engagement. After pushing back I was escalated to the founder, Ty, who was excellent. He handled the situation professionally and refunded the months in question. To prevent future billing issues he suggested migrating me to their new V2 beta. Unfortunately that decision has been a DISASTER. The V2 beta is highly unstable and introduced multiple serious problems. Upsell data was migrated incorrectly, with deals that required $110 spend reset to a $40 default threshold, something very easy to miss unless you manually check every upsell. This meant customers could unlock significant discounts far below intended spend levels. The cart itself became buggy and unstable, crashing, failing to load images and freezing pages. I was unable to roll back to V1 once migrated, and even disabling upsells and turning the cart off did not fully remove it. A broken version of the cart continued overriding the default Shopify cart. My only option was to uninstall the app entirely to remove the malfunctioning cart from my store. This is particularly frustrating because the app had previously performed well and helped increase AOV, but migrating a live high-volume store to a beta version on a Friday, leaving no weekend support, resulted in significant revenue loss. I am disappointed to leave a one-star review as I respect Ty as a founder and have enjoyed using this app, but based on this experience I cannot recommend it.

Had an issue with shipprotect checkout and Angelica from the support team handled it with ease. The issue was resolved quickly.
