YITH WooCommerce Product Bundles is an extension conceived to create bundles with the combination of some products of your shop. You can assign an ad-hoc price to the bundle or a price given by the sum of the single elements contained in the bundle itself.
The plugins can be perfectly integrated and allow setting the minimum and maximum purchase quantity for the “Bundle” products. Moreover, you can choose whether to apply the quantity rules to the bundles or the bundle items as shown below.
If the quantity doesn’t meet the configured requirements, users can’t add the bundle product to the cart, and a message will show to notify them about the quantity required to proceed with the purchase.
