About the Mergerate: Combined Shipping
Mergerate solves the split-cart shipping problem when orders ship from multiple locations. Instead of charging shipping rates twice, this carrier service combines your rates into one shipping charge per order while showing $0 for additional shipments.
The app works with carrier-calculated shipping and lets you set your own flat rates by country with delivery estimates. When a customer's order splits between locations, Mergerate returns your chosen shipping options on the first shipment and displays the same options at zero cost on others, complete with custom labels and delivery timeframes.
You can configure flat prices for different countries and track everything through the request log, which shows each shipment and the rates Mergerate returned. This works best with flat rate shipping and requires carrier-calculated shipping on your Shopify plan.
