Shipping calculator: ShipMagic

ShipMagic solved a shipping setup that we couldn't achieve with Shopify's native settings. We needed different shipping rates for our main products and add-ons, while avoiding additional shipping charges when they are purchased together. The app handled exactly what we needed without requiring CCS or a Shopify plan upgrade.

Their customer support was also incredibly helpful and responsive. They even checked our store directly when we had trouble with the setup. Highly recommended!
