Product Bundle helps merchants sell more per order with four bundle types: classic, volume discount, BOGO, and mix and match. Set your discount, and the app auto-embeds the offer on matching product pages through a theme app extension. Discounts apply through Shopify's Cart Transform and Discount Functions, so totals stay correct at checkout, Shop Pay, and accelerated checkouts. Customize fonts, colors, and badges per bundle, then track revenue and order value uplift in the analytics dashboard.
