How to adjust shipping charges for multi-location orders?

Topic summary

A merchant with three stock locations (including print-on-demand and fulfillment centers) wants to charge £3.50 for single-location orders and £5.50 for multi-location orders. Currently, Shopify automatically charges £3.50 per location (totaling £7.00 for two locations), which the merchant considers too high.

Technical Limitation:
Shopify treats multi-location orders as separate mini-orders and automatically adds shipping rates together. Third-party shipping calculator apps cannot distinguish between single and multi-location orders due to how Shopify sends cart data.

Proposed Solutions:

  • Intuitive Shipping: Suggests consolidating all products into a single location and using product tags/conditions to create custom scenarios. This achieves desired pricing but sacrifices proper location inventory tracking.

  • Bespoke Shipping: Claims to have solved the multi-origin shipping issue. For flat/price-based rates, works on Basic plan. For live rates, requires Shopify plan with Carrier Calculated Shipping (CCS).

  • Alternative workaround: Make print-on-demand items free shipping by incorporating costs into product prices, charging only for warehouse items.

Status: The discussion remains open with potential app-based solutions identified but not yet tested.

Ok, well just online to support and apparently I need a Shopify App Store
that allows you to create custom shipping rules based on the number of
locations involved. It looks like it is possible, I just need to select an
app.
