Upzella: Bundle Builder

Upzella Bundle Builder lets customers create their own product bundles and unlock tiered discounts as they add more items. You set the discount tiers — for example, 2 items save 5%, 4 items save 10% — and a live progress bar shows shoppers how close they are to the next discount level. The app adds a "Build Your Bundle" page to your store where customers pick from up to 20 products you choose. Helpful nudges like "add 2 more to save more" encourage larger orders. Discounts apply automatically at checkout using Shopify's native discount system — no coupon codes needed and fully compatible with Shop Pay. Installation is simple with a native theme block that requires no external scripts. Customize colors, labels, and layout directly in the theme editor with live preview.
