No, I am not worried about some type of "secret".

As a buyer, I want sellers to send by appropriate posting method that is fitting with dollars paid.

As a seller I send by appropriate posting method for $$$ value of purchase and offeres best protection for buyer and seller.  Not moral motivation, its just good business.

As a citizen I don't want our ombudsmen, financial services or postal, tied up with issues that are essentially based on poor paypal wording - there are far more important matters that ombudsman were set up to do - truly protect consumers - not reward retailers for not sending goods by appropriate methods that are readily available, albeit more expensive in last week or so.

As a discussion board poster and ebay buyer and seller, I don't want other posters to encourage others to post goods by method that is not in best interests of any customer on ebay, IMO t doesn't help buyers or sellers or build safe trading environment where buyers can have confidence that there are safeguards in place.  I do wish buyers knew about alleged seller protection regarding post proof, but most buyers only simply don't, nor should be expected to.
