I have the Ruby script example for line item bundle discounts…however I am looking to specify ANY product from a collection vs. an individual product.
How might this script be adjust to accommodate my need? Script for reference: https://help.shopify.com/en/manual/checkout-settings/script-editor/examples/line-item-scripts#bundle-discount
Example: buy 1 from collection A AND 1 from collection B, receive 10% off the item from collection B
Example: buy 1 from collection A AND 1 from collection B AND collection C, receive 15% the item from collection C
