Bundle Builder
Build a "build your own box" page where customers pick their own products.
Welcome to the Bundle Builder docs.
A Bundle Builder lets customers assemble a custom bundle on a page you choose — "Build your own gift box: choose 3 candles, 2 soaps, and 1 bath bomb. Save 15%." You define the categories, the box sizes, and the discount; customers do the picking.
Bundle Builder is the BYOB ("build your own box") half of Oxify Quantity Breaks & BYOB on the Shopify App Store.
