How to build a mix and match bundle discount
Once you've installed Simple Discounts, you can create a mix-and-match bundle discount directly from your Shopify Discounts tab.
Go to Discounts on your Shopify Admin > Click Create discount > Click Mix-and-match bundle discount
On the mix-and-match bundle discount editor, add your discount title, quantity and collections, discount percentage, and other discount details. Then click Save discount.
Test your discount by adding eligible products to your cart from your online storefront or POS. The discount will be added either automatically or by using a discount code based on your selection in your editor. Your customer can see the discount applied in their cart and you can see the discount applied in your orders.
