An Amazon authorized 3rd party seller listed something at a deep discount. I had a price watch set up so I was notified immediately. The price seemed a bit too good to be true, but the seller had several 4-5 star reviews and I figured it was Amazon, so must be legit, and I’m protected if not. I placed my order immediately because I thought price might change.
