I once priced a variety of scales on Amazon and for weeks afterward the stream of recommended products that Amazon shows at the bottom of the page became polluted with all sorts of drug paraphernalia that Amazon sells.
My takeaway is that drug dealers/users use Amazon to buy their supplies just like anyone else. It makes sense, I mean, why wouldn't they?
I was at a punk bar in Boston, and, a little drunk, walked up to one of the scarier-looking punks and asked about his jacket. He told me how he spiked the entire thing, put in the studs, and sewed on all the patches. I asked "where did you get the spikes?" he replied "Amazon, mate!"
The article calls these "high-powered, expensive scales" which seems like a weird thing for a blog that's all about prices of things to get so wrong.
