SHOPIFY BUNDLE APP EXPLAINED

What does Rebolt Bundle & Upsell do?

Rebolt is a Shopify bundle and upsell app that lets merchants sell related products together at a discount.

Product Bundle

A fixed bundle sells a set group of products together at one discounted price, added to cart in one click. Raises AOV by selling several items per order · Moves slow-selling stock alongside best-sellers · Makes gifting and "starter kit" decisions easy for shoppers

Frequently Bought Together

A frequently bought together widget shows products often purchased with the one being viewed, so shoppers can add the whole set at once. Surfaces complementary products shoppers would otherwise miss · Adds extra items without extra ad spend · Works on every product page automatically

A cross-sell bundle recommends related products from other collections to complete the purchase. Increases units per order across categories · Helps shoppers discover more of your catalogue · Builds "complete the look" and full-routine purchases
