Assemblify

Assemblify lets customers build their own custom box from products you choose. Shoppers can select exact variants, drag items into a box, name their collection, and see the live cart total before checkout. You control which products are eligible, set how many pieces are required, and customize packaging finishes and copy. The app works through a theme app block that you can publish on any page or product template. Bundle discounts are applied automatically at Shopify checkout using discount rules you configure—either fixed-price or percentage off. Customers get a personalized shopping experience while you increase sales through curated product bundles.
