Hi all,
We’re trying to implement a rule on a Shopify Plus store where a specific product (tagged, e.g., no-discount) should never receive any discount allocation, while all other cart lines should continue to be discounted as usual.
We’re aware that this can be handled cleanly using Shopify Discount Functions by filtering targets. However, our store relies on a large number of existing native discount codes, automatic discounts, and app-generated discounts, which makes migrating everything to Functions impractical.
Given that, is there any mechanism (checkout validation, cart transform, or otherwise) that allows us to prevent discount allocation on a specific line item when native discounts are applied?
Or is it fundamentally not possible due to how Shopify distributes discounts across line items?
Would love to hear how others have handled similar constraints.
Thanks in advance ![]()
