I have a friend in Germany that is in a Facebook group for "testing" products from Amazon. They need to purchase all kind of weird and low quality stuff from unknown Chinese brands, they keep the product, get a refund through Paypal and leave a 5 star review. I told him it's kind of a bad thing to do, but hey, free 29 Euro earbuds. :) I knew this was a problem mostly in the US, but just like one of the initial commenters noted, it's starting to happen even in Germany, and Amazon is now filled with all kind of weird cheap brands that have 4,5+ stars and 500+ reviews, you can't get any proper stuff like a humidifier or some small kitchen accessories without being flooded with spam. Well, back to local shops and retailers.
