I keep getting packages in the mail that are addressed to me, but not things I ordered. Lawnmower parts, plumbing hardware, a grill cover, a magnetron (!), etc.

One had an amazon slip in it, but most of them have come through ebay. I reported the one to amazon and the rest to ebay (I gave them the USPS tracking numbers since I didn't know the order numbers), and also contacted a couple of the sellers who were businesses with public contact info. The sellers I reached both said they would send me return labels, but neither has yet.

I feel like this has to be a scam, but I'm not sure exactly what the scam is. Maybe someone's writing fake reviews, but making real orders to match?

This is the reason I stopped selling on eBay. Zero protection for the seller.
