ZeroBloat Bundles helps merchants create tiered volume discounts and bundle offers directly in the theme editor. Customers can select quantity breaks with custom percentage discounts or build bundles using interactive checklists. The app runs on native Shopify Functions for automatic checkout discounts and includes optional countdown timers for promotions. Built as a Theme App Extension, it keeps store code clean without injecting external scripts.

• Quantity breaks with customizable percentage discounts per unit.
• Mix and match bundles with interactive checklists and variant selection.
• Urgency countdown timers with evergreen session and fixed date modes.
