"I do wish buyers knew about alleged seller protection regarding post proof, but most buyers only simply don't, nor should be expected to."

Well, who has been telling them the wrong information re "alleged seller protection proof"???

If you have been spreading PP's BS propaganda because you believed it as well the you are part of the problem not part of the solution...

Buyers need to be aware that if more than one postage service is offered then it is their responsibility to select the most appropriate form of freight and security for the item offered.

Sellers need to understand that by offering more secure forms of freight, and availing the buyer to the risks involved and who is liable for the loss that they have (benerally) met the deemed delivered terms in the SOGA
