Sure, because the sellers were willing to work with you. What you got didn't come from Ebay. The "buyer protection" says something like:
If you buy a book and they send nothing, you'll get your money back If you buy a book, and they send you a crappy book, you're SOL If you buy a book and they send you a doll, you are guaranteed price paid plus original shipping, once you send the doll back. Why should you have to pay for return shipping for the sellers mistake?
Then when you amplify this non protection system, you get a scenario like one I had: Through Ebay, I asked a seller if an implement would fit my skid steer. His reply, "yes it will". (Note: these are new, the seller is a fabricator) I buy the implement , pay for it plus shipping $420. I receive it, and it's not even close to the mount of my machine. I contact him, through Ebay to correct the situation and I'm ignored. I file with Ebay through "buyer protection system". Seller contacts me, offers to pick up implement and refund me or pick up implement and deliver one that fits my machine. I choose getting an implement that fits my machine. Seller neither picks up or delivers promised implement as offered. I go to stage 2 through "Ebay buyer protection", and half an hour later they email me. They've reviewed my claim and rule in my favor. Just send the item back to the seller, and I'll get my $420 back. After about an hour I finally got a human from Ebay on the phone to explain that shipping a 500 pound implement 1000 miles will cost me $400, and to explain to me,why there is no burden on the seller to pay for his mistake. Totally fruitless effort, I may as well been talking to a rock. "That's our policy", and stop yelling at me or I'll disconnect.
