If you have chosen to receive the automatic calculated shipping rates at checkout, you may want to slightly increase that shipping fees to compensate the postage or any other expenses related to the order fulfillment.
You can adjust the rates with the help of the Shipping markup option. The fee will be added on top of the shipping rate provided by the carrier company and will not be explicitly displayed at checkout unlike a handling fee.
To add a markup to the carrier-calculated shipping method:
- Go to your store Control Panel → Shipping & Pickup.
- Click Actions → Edit for the configured carrier-calculated shipping method.
- Under the Shipping settings block find and fill out the Shipping markup field with a flat amount that will be included into the shipping fees.
- Click Save.
