How can I export shipping data including box size, weight, and cost?

UPDATE

I just spoke with Shopify support, and they figured out a way to get the info:

  1. go to Settings > Billing

  2. Choose the bill you need

  3. Click Shipping - It should show a number of “items”, which are the shipping charges.

  4. You can export each month as a CSV.

Not as neat and tidy as a single report, but not crazy either.

Hope that helps.
