We have two couples living in our house and receive 5-15 Amazon packages a week and have never had a single "OMG this is counterfeit/fake/literal garbage" moment. And all of us LOVE to complain about any opportunity that has a sliver of a chance at a discount. Meanwhile, I have read numerous HN accounts of "OMG, Amazon is always sending me counterfeit/fake stuff"
At this point, I'm honestly thinking there are troll(s) on HN bashing Amazon. Also, the returns are EASY, so... What gives? I hate that Amazon is TBTF and Bezos controls more resources than some Nations, but the facts for me are: Amazon delivers what I want very quickly at reasonable prices. They often have items that I literally cannot buy locally. I wish I could always support my local people, but often as not, Amazon does a better job with less friction.
Seriously? 7\10?? You buy 10 widgets and (want to) return 7 of them? I'm just going to say this now: you are either pulling numbers out of your ass (on a technical-loving web site) or you are outright lying.
