Recently, while browsing for computer parts I don't need, I came across a 1050W power supply on Amazon listed for $50,000. I also used to have a screenshot (which I unfortunately can't find right now) of a really cheap looking off-brand pair of headphones on eBay, the kind you'd find for sale in a drugstore, selling for over $1200, with the words "Solo para la familia". Are these sellers just being silly or are they really, really hoping to just sell one? Or is this a form of money laundering?
Apologies in advance if this is the wrong place to ask this, but it relates to money and I'm not sure where else to ask it
