Rich Bundle Builder helps you create a Build Your Own Bundle (BYOB) experience with a flexible product bundle builder. Shoppers can mix and match products through multi-step flows while automatic discounts apply based on their rules. The drag-and-drop builder lets customers select from products or collections with live preview as they build a box bundle. Set up amounts, quantities, or fixed discounts that automatically apply to bundle items. The AI-powered styling studio customizes colors, fonts, and layout to match your store. Track performance with built-in analytics showing views, conversions, revenue, and AOV comparisons. The theme app extension includes a BYOB widget with countdown timers and stock counters to drive urgency. Perfect for improving average order value and conversion rates through customizable product bundles.
