I don't recommend this app. Their pricing model is unfair — they automatically increase your charges when you upgrade your Shopify plan, which frankly is none of their business. What Shopify plan you're on shouldn't dictate what you pay for a third-party app or how much service they're providing. On top of that, most of their features can be replaced with Shopify Flow.

Hi Bilel, thank you for your feedback. We understand your concerns regarding our pricing model. Like most apps on the Shopify App Store, we align our charges with the store plan, as it reflects the level of service provided. We strive for transparency, and our tiered pricing is clearly outlined in the app listing prior to your installation. If there's anything else we can assist you with, please let us know!

Great app! Super intuitive and easy to use, especially for managing bundles and keeping stock perfectly synced. It’s been a huge help for our store. The support team is also excellent And a special mention to Ian — his support is fast, clear and truly helpful.

Stop searching for a bundle app and just get this one.

Bundle Kit is a reliable, user friendly app that handles bundling logic cleanly and efficiently. Setup was straightforward, and it integrates seamlessly with multiple locations.

Support has been excellent, quick, knowledgeable, and helpful. Highly recommended.
