Create mix-and-match bundle builders that let shoppers build a box their way. Publish a build-your-own-bundle landing page with steps and a live summary, or place the builder on a product page with slots or an inline catalog. Set tiered discounts per box, show a progress bar and unlock a bonus gift. Add an add-on step, gift notes and gift packaging. Control steps with quantity, spend and compatibility rules. Track every builder with funnel analytics, A/B testing and storefront translations.

• Place the bundle builder on its own landing page or directly on a product page.
• Reward bigger boxes with tiered percent-off, amount-off or set-total discounts.
• Show a progress bar that unlocks a bonus gift when shoppers reach a box size.
• Let shoppers add extras, gift notes and gift packaging to make any box a gift.
• Find the step where shoppers drop off and A/B test builder variants.
