Bristm Upsell & Bundles App

I’ve worked with Bristm Upsell & Bundles to implement and customize bundle, upsell, and volume discount experiences on Shopify stores. My work included configuring the app, integrating the widgets into the storefront, and customizing the presentation to match the existing theme and UX.

I’ve also worked on the frontend side to make sure the bundle and discount components were responsive, clear to customers, and integrated properly with the product and cart experience. When issues came up, I was comfortable inspecting the app-generated markup and JavaScript behavior, troubleshooting conflicts with the Shopify theme or other apps, and implementing custom solutions where needed.

Overall, I found Bristm useful for quickly implementing bundling and upsell functionality while still allowing enough flexibility to customize the customer experience around the store's design and CRO goals.

Does exactly what we need – bundles in our online store and at POS

The app (formerly Rebolt Bundle & Upsell, now Bristm Upsell & Product Bundle) does exactly what we need. It works at our POS and in our online store. Bundles can be set up easily and integrate well in the buy box. We have been using it since May 2026 for our yoga and meditation sets, and we can keep our own SKUs and EANs, so inventory and our marketplace setup stay unchanged.

The support was super fast and helpful with all our questions. When the app rename temporarily affected our POS tile, the team investigated right away and fixed it within a day.

Two small suggestions for the team:
- Add-to-cart tracking: a bundle is sent as one request with several line items, so depending on the theme and tracking setup, events can fire for the bundle and for each product. A native bundle-level event or clear tracking documentation would be great.
- The buy box content loads slightly slower than the rest of the page.

Overall, a great and flexible bundle solution for merchants who sell online and in-store. Highly recommended!Also the support was super fast and helpfull with all our questions.

This app is great.. We've definitely seen a big difference in customers and sales since bundling our products with this app.

We use Rebolt to manage all of the product bundles at our Shopify store, and it has been an absolute lifesaver. Our store has some very complicated bundling scenarios, but this app always manages to find a solution that works perfectly for us.
What really sets them apart, though, is their customer support. They are incredibly helpful, responsive, and went above and beyond to help us achieve all of our custom solutions. If you need a flexible, reliable bundle app backed by a stellar support team, look no further!

It's a really good app. It plays a big role in increasing sales, and the support from the custom center is the best. I've compared other apps, but this is the one I recommend for promotional sales.
