Cinch ‑ Bundles & Free Gifts

Cinch is a no-code bundle builder that lets customers assemble their own bundle and check out in one step. Set up a build-a-box in minutes: choose which products can go in, set the box size, and add a bundle widget to any product, collection, landing page, or cart. Reward bigger bundles with tiered savings or an optional free gift, schedule offers, and target specific products. Bundle pricing is enforced at checkout by Shopify Functions, so it stays correct even under heavy traffic.
