I rarely, like once every 6 months, look for some obscure thing on Amazon. First thing I do after finding products, I research which one of the listing has any chance of not being a fake/dud/scam.
I can't imagine buying anything of value on Amazon.
It varieres from region to region obviously, but here there's no point in ordering from Amazon. Everyone else is cheaper, have faster shipping and don't have a ridicules number of scamming sellers with fake, defective and dangerous products. It seems like Amazon should be failing, but I don't think they are.
The Amazon store really have become an absolute shitshow.
Amazon definitely explicitly supports this.
What I do, is go directly to the product Web site (not the Amazon page for the manufacturer), and order from there. Sometimes, the fulfillment is via Amazon, but I know I’m getting the real thing. The difference in price is often smaller than you might think. Amazon prices aren’t that good, anymore.
