I have a story that's similar. I have a bunch of cars, mostly seldom driven vintage cars. I'm forever in need of fresh batteries, because I always forget to set up the chargers. One day, I spot someone offering two AGM batteries for $100. He had bought the batteries for a truck or motorhome, and it was wrecked before they were installed. It seemed too good to be true, but what the heck. So I bought the batteries, and paid another $50 to have them shipped. A few weeks(!) later, I was surprised when UPS delivered a crate from a well known TV ministry (name withheld). Inside, were two of the grungiest batteries I've ever seen. I mean, these things must have been fished out of a mud hole, then rinsed in swamp water. Not only were they dead, the were nonchargeable. So I wrote the seller and said, here's what we both now know. 1) You sold me two useless batteries and 2) You stole the postage from a church. (I'm not religious, but there has to be some commandment about stealing from a church). He said that the batteries were perfect, but he'd happily return my money if I returned the batteries. That meant another $50 shipping charge. So I filed a claim with paypal. Paypal said that as long as he was willing to take them back, it was my responsibility to ship them. I dinged his feedback, and returned the batteries. My total cost for the batteries and two way shipping was $200, but at least it I would recover $100. It took Paypal months to get the money back for me. And when it was all over, he filed a protest with E-Bay, which converted my negative feedback to neutral because he had returned the cash. This was some years ago, policies may have changed, but I'm still very cautious.
