Bundly makes it easy to sell mix-and-match, build-your-own (BYOB), and fixed bundles from your existing products and collections. Set min/max selections and quantity rules, then price bundles your way: fixed price, component total, percentage off, or amount off. Inventory is tracked per individual product with no syncing needed, and bundles can stack with existing discounts. Ideal for gift boxes, kits, and curated sets. Not compatible with POS or subscription apps.
