In a perfect world, yes COD is indeed the seller delivering however possible : IF the seller knows the true meaning of COD. However, as stated earlier most don't, and delivering a 3pce lounge (as example) could be tricky if the seller is in WA and Buyer is in Tas. All I am trying to say is that an error like that can cause headaches for all concerned, and IMO would be better off not being an option.
