Biscuits only works with default product prices.

This means Biscuits does not currently work with catalogs and price lists from Shopify Plus B2B.

If you are not actively using catalogs for pricing changes, and only have standard pricing for your products when using Shopify B2B, Biscuits will work as expected.

If you have a use-case for needing Biscuits to work with Shopify B2B - we'd love to hear it as we hope to support B2B bundles in future.
