Do people really care about Black Friday that much ? Also why 20countries ? Isnt Black Friday mainly an American thing ?
Those problems were much worse a few years ago, but instead of eBay getting significantly better, Amazon got much much worse. Amazon is being flooded with cheap knockoff Chinese products that often seem very questionable in regards of quality and safety.
For many things that I end up buying I just use a shopping search engine such as Geizhals or idealo. It is very very rare that Amazon is among the cheapest shops for any product I'm looking for
This was the first year I've noticed it in Europe.
