Some of you may have already seen this: a thread about ebay and the Chinese reborn knock offs
This is an excerpt from The Atlantic, which is mentioned in the thread.
“We send [manufacturers] data about what people are looking for on eBay and they respond and turn it around incredibly quickly,” president of eBay Marketplaces Devin Wenig told me. "We have a really big China export business to Europe and the United States. And they respond very, very quickly to consumer taste, whatever it might be. It’s really remarkable to see how quickly the manufacturing base adapts to the demand signals they get.
After reading the complete thread it’s obvious it’s a problem in every ebay category. Pretty sad.
