Bundles & Buy One Get One App.
Bold's Bundles App is the best way for retailers to bundle products, sell kits, sets and offer volume discounts or quantity breaks in their Shopify Store! Bundle a few products or entire collections so shoppers can mix and match to get a discount. Automatically promote product bundle discounts on sales pages so customers can see how much they'll save. Uses Shopify's inventory management so merchants can boost revenues via bundling without creating new variants for every bundled product combo.
