Different products, different shipping rules

One SKU that can't fly ruins air shipping for the whole cart — but Shopify's native settings can't see what's in the cart beyond weight and price.

Drydock's conditions read products, tags, vendors, and collections, including mixed-cart logic (“contains A and B”). Pick the tricky SKU in the simulator's cart builder and watch the option list change.

Test first. Undo after. Always.

Drydock runs every draft rule against a synthetic checkout — real products, any address, any customer — and shows a trace of every condition with the actual values compared. Save good scenarios as test cases and they re-run on every publish, so a rule that changes an outcome gets flagged on the publish screen instead of at your checkout. Every publish is an immutable version with a diff, and restoring a previous version is one click.
