I was following up yesterday, and Iknow mine are good. All signs point to Amazon overreacting (which in this case is probably a good thing). On one of the tech sites, a guy posted that they refunded the money on the $150 solar filter he bought for his camera lens. I forgot the brand, but he seemed to know what he was talking about regarding astrophotography, and said the name brand filter came in proper packaging, etc. and was absolutely genunine.
So as mentioned above, it appears Amazon is just not taking chances, and is working off hearing back from their various resellers, versus actually checking the products their vendors are selling. So if a vendor didn't respond in time, Amazon defaulted to sending out the email and issuing a refund. That's gotta be costing them a boatload of money.
