Recently my mother threw out a bunch of Christmas decorations because "they gave up the ghost". What had actually happened is she got counterfeit energizer batteries from amazon (which had 5-star reviews ofc). This story is not that big of a deal, but perfectly emblematic of the mess that is Amazon's store and hardly the only bad experience I have had with the junk they sell there.
Also this has been going on for years now and amazon has done _nothing_ to address it. I suppose it's because people keep voting with their dollars for them to do nothing. Maybe now they'll start to think about it.
