Interesting. There are many sellers who lose lots of sales because instead of using the cheapest form of shipping available, they use the more expensive tracking with signature confirmation option. But even with signature confirmation the buyer can claim empty envelop and still get his money back.
I have a cousin who owns a brick and mortar store. When asked if she is worried about employee and customer theft, she simply answered, "it is all in the program" ie. it is the cost of doing business. I can understand you, and if I was a seller, I would feel the same way. But try to think of it more philosophically. Thefts occur in at businesses. It will at least take some of the sting away.
Many experienced ebay sellers say to add a couple of dollars extra to shipping charges and put that money in a jar. When thefts occur, to take the money from the jar to cover your loses. Just an option.
