Amazon blew it when they invited 3rd party sellers. When it was just Amazon + Their Warehouse you knew what you were getting.

Even when it is fulfilled by amazon you don't have any guarantee it's not fake.

I wanted to buy some Tasty Bites meals. Normally I get them from Costco but they only have one kind and I wanted to try some other flavors. So I went online, found them on Amazon, and literally said to myself "I'd rather buy these directly from the manufacturer". So I went to tastybite.com and filled up my shopping cart and when I went to checkout, it redirected to amazon.com which asked if it was okay to put these items in my Amazon cart.

Amazon is de-facto a monopoly. The "invisible hand" does not apply here.

No, Amazon is not a monopoly, they are a very large and influential player. You can still buy eclipse glasses (and practically all other products) from other vendors, both physical and online. It may not be as smooth, cheap, fast or convenient as Amazon, but that's pretty damn far from the bar for a monopoly.

There was never any guarantee that the invisible hand would fix badness overnight, merely that it will nudge them in the right direction. Which it does.

Not anymore, you can't. Just about every supplier on the Internet is sold out at this point.

That's what the civil court system is for. Nothing invisible about that hand. They are in a world of $#!+ if anyone receives permanent eye damage from counterfeit glasses purchased on Amazon, especially if their insane "inventory commingling" policy turns out to be implicated.

The article only talks about the sun appearing too bright through counterfeit glasses, but the real hazard is a pair of glasses that blocks out enough visible light to allow your pupils to dilate, letting in plenty of the UV they don't block.

I love how you spell $#!+.
