Coverage counts what each App Store listing names. Every feature, checked off app by app, is in Shoplist.
See every featureWhen an order ships from more than one location, Shopify adds each location's app and carrier rates together, so a split cart can be charged shipping twice. Mergerate is a carrier service: it charges your own rates on one shipment and returns the same options at $0 on the others, with a label you choose. Set flat prices, countries and delivery estimates; it works best with flat rates.
Merchants can create custom shipping rates instead of relying on a single fixed carrier rate. Each rate combines a base amount with optional surcharges for weight or order value, and can be limited by minimum or maximum thresholds.
