Shopify Bundles

The idea is great to combine individual SKU's into bundles but the app works only when both the individual SKU's are showing same qty. Even 1 sku goes down by 1 number, the bundle shows that combo as not available instead of showing the minimum available qty of any sku in the bundle as the combo qty.
Hope this is sorted out. Uninstalled as it lead to our combo's showing out of stock most of time.
