Simple Bundles & Kits

Absolutely, no doubt, 100% the best bundles app in shopify. "Simple" is for simple of use, but the features that this app provide are much complex and helpful. We use this app with all of our clients and we will keep using it whenever we need bundles management.

I've used this app to create bundles for apparel (so, with multiple sizes and colours per SKU) - and it works flawlessly. Also: customer service is definitely on-point!

This app was not for us. All we needed was a simple way to sync the components/products associated with bundles we were already selling on our store. But there were far too many caveats for us to move forward. What's not obvious from the app description:
Their default method breaks out the individual products in to separate line items on the order and discounts them 100% (screwing up your inventory reporting), but also adds the bundled SKU as its own line item (inflating your units sold). Their alternative method still breaks out the individual products but doesn't add the bundled SKU. But this effects your ability to discount properly and leave you with no way of knowing how many bundles were sold.
