Upzella: Bundle Builder

Upzella Bundle Builder lets customers create their own product bundles with mix and match options. Shoppers can build a box by selecting from products, collections, or tags you choose. The app features quantity breaks with tiered discounts that automatically increase as bundles grow, plus a live progress bar to encourage larger orders. Run BOGO promotions and buy X get Y offers that apply automatically at checkout—no discount codes needed. Add optional gift wrap to bundles for extra value. Built as a native theme app block, it requires no coding and has zero speed impact on your store. All bundle discounts work as real Shopify automatic discounts, making them Shop Pay ready for seamless checkout.
