Cable Burn-In Question Interconnect & Speaker

With the known fact that Audio Cables (Interconnect & Speaker) benefit greatly from the Burn-In process...I see more Cable Retailers offering a Burn-In Service.

Curious, do most of you Hi-Fi experts prefer to burn the Cables in yourselves?

Or, do you pay the Cable Retailer to burn the cables before they are shipped to you?

Any information you can share would be greatly appreciated!
