Hi SAAINTUARY team! Thank you for trying Duplicup. I am so sorry to hear about the items being added to your cart twice. While our app typically runs only in the background and doesn't interact with the cart, we want to be absolutely sure we understand what happened here. We would be more than happy to look into this with you and help get it fixed, whether it's an unexpected interaction with our app or a theme conflict. Please reach out to our support with a few details on how to reproduce the issue so we can investigate and solve this together!

We looked all over for a solution and finally found this. We had a specific issue that required some some custom coding to get it working. Aviad was always on top of it and went above and beyond to make sure Duplicup worked perfectly with our store. Highly, highly recommend.

I’ve tried several other apps for managing shared inventory across variants and locations, and none of them quite delivered. This one finally does. Everything stays perfectly in sync, which has saved us a huge amount of time and eliminated the constant headaches we used to deal with. What really sets it apart is the support. It’s incredibly fast, genuinely helpful, and the team goes above and beyond. Any time we’ve reached out, we’ve gotten clear, thoughtful responses almost right away. That level of care makes a massive difference. If you’re looking for a reliable solution that actually works, this is the one. Highly recommend.

We needed a slight tweak to an existing feature and we reached out and the devs had the feature added within a few days. No other SKU sync tool lets you manually link product skus. This is a game changer for our business and quite helpful. Thanks so much!
