Discount codes can be added through your Shopify admin space to create fixed value, percentage, or shipping discounts on products, collections, or variants in your store.

Shopify does not allow discount codes to be applied to any draft orders, and this unfortunately includes all third-party apps which rely on draft orders to function. This is therefore an obstacle which many third-party apps face when using draft orders - not just Bundle Builder.
