Rebuy Personalization Engine

I installed this app hoping it would improve my store, but it turned out to be a costly mistake. The setup is unnecessarily complicated and requires constant technical adjustments just to achieve basic functionality.

After spending hours customizing it with CSS, I ran into multiple bugs that caused my cart not to display correctly. The result: direct loss of conversions and sales. It’s unacceptable for a revenue-focused app to negatively impact revenue.

Support did respond, but none of their suggested “solutions” actually fixed the issue. I even switched themes to rule out compatibility problems, and the issue still persisted. The cart would work intermittently — completely unstable and unreliable.

For the price, the quality is extremely disappointing. The interface feels outdated, unintuitive, and far from professional. It does not meet the standards of a serious ecommerce business.

In short: this app cost me time, money, and lost sales opportunities. I absolutely do not recommend it. There are far better and more stable alternatives available.

Rebuy Engine - Deceptive Billing, Broken Agreements, and Merchant Exploitation: Avoid at All Costs

Fellow merchants: Steer clear of Rebuy Engine. Their tactics erode trust in the Shopify ecosystem and could cripple your operations. Don't let them exploit you. Full review will be up soon.

Its so frustrating.
I added the app and after looking at the help sections, I felt so overwhelmed by it all.
The cost was a shock too. 44.00$ for an app that allows me to build bundles.
No thanks!

The support is a joke really, I have never experienced such an arrogant and unhelpful approach as with Rebuy (I've been writing with Zara). Very very unhappy

Had amazing support agents before, especially Jessica.

Now my cart is outdated because the way rebuy software was set up.

So i have tried setting it up but it has been a really jarring experience, only because of the support agents i have met.

I feel like the Rebuy team has not cared at all to help me update my cart, the design is already done and has been fully designed by rebuy before.

But they will not help me at all this time.

This app sucks. Stay away from it!!!!
SmartCart not working. I've gone through all the help docs and none of them helps because none of them are up to date!!!!!!!
Don't even bother with free trial, because their human support isn't there
If you don't want to waste 2 hours of your life for a setup that is supposed to be no-code and easy, just stay away from Rebuy

We had a very frustrating experience with Rebuy. As a business, Wild Oak Boutique invested $1,500 for their developers to perform custom work on our smart cart, in addition to their $999 monthly subscription. However, the code they implemented caused a major issue on our website that was isolated to Safari browsers. The bug created a loading issue that made our website appear frozen to customers, resulting in an estimated $25,000 in revenue loss before a third-party developer finally identified and fixed the problem.

Despite the obvious impact on our business, Rebuy refused to offer a refund for the custom work, citing the effort they put into it. For a service at this price point, we expected a much higher level of quality and accountability. Their unwillingness to take responsibility for the issue has left us feeling undervalued as a customer. They were only willing to offer a credit if we continued using them.

If you're considering Rebuy, proceed with extreme caution, especially if you're relying on their paid development services. We wouldn’t recommend them.

Fantastic app however not compatible with our wholesale pricing app. I also for some reason had access to someone elses store/rebuy login..i could literally make changes if i wanted.... A bit of a worry. They said they fixed it but i still had access.
Since uninstalling rebuy our cart function dosent work anymore and also have no acces to developer help to remove whatever code has been left behind (which i was told all code would be removed) please help, this is affecting my business

You will receive no support from this support team.

the App broke my theme several times, when contact the support I was offered initial setup for 700$ something un acceptable. The App interface is heavily to understand and not intuitive at all. Overall BAD Experience and waist of time.
