Sale of a service without shipment costs?

Having mastered (well, sort of…) the shipment costs feature, I’m now confronted with the question how to sell (e.g. a service) without shipment costs?

As a workaround, I created a shipment product “V0 - free of charge” with price 0 - but that’s not really elegant. Does somebody know a better solution?

Cheers,
