Configure shipping zones and rates

Set shipping zones so continental United States uses Standard and Expedited options, Alaska and Hawaii get Expedited only, and Canada has a single flat rate. For orders under $50 in the continental US, charge $6.95 standard; for $50 and up, free standard. Set expedited to a $15 flat fee regardless of order value. Apply these rates starting immediately and notify fulfillment and customer service.

Before I finalize shipping zones, make the rates easy for operations to audit. Show which SKUs are excluded from certain zones, surface average shipping costs by zone for the last 90 days, flag any postal code exceptions, and call out third‑party carrier surcharges so leadership can judge margin impact.

I updated shipping rates to add a $15 expedited fee and immediately got three calls from customer service about unexpected charges for Alaska orders. I’m worried we misassigned zones or carriers. I can’t see recent carrier surcharge changes. What likely caused this and what’s the fastest way to verify and fix it before more customers are billed incorrectly?

We keep losing credibility because shipping zones and rates are adjusted ad hoc, leading to surprise fees and extra CS workload. I want one procedural change to stop rate mistakes and reduce support tickets. What recurring review, owner role, or automation would prevent the same errors across launches?
