Has anyone ever really given much thought about the high cost of shipping on ebay?

Ebay has become entirely ridiculous with the shipping cost with some sellers. I know a lot of them do it to avoid Ebay fees but it’s a scam! Especially if some unsuspecting buyer gets on there and doesn’t notice the outrageous shipping cost. I was on there the other day I saw an item that was priced at $40 US dollars and the shipping was $500! Why doesn’t Ebay do anything to control this growing problem I wonder?
