Show me the money!
Normally I don't even bother looking around since Mr Friendly does an amazing job at highlighting things like this but I found the numbers in this article to be absolutely amazing.
"The data showed that scalpers made up to $946,259 in earnings from flipping Zen 3 processors on eBay. Nonetheless, the scalpers weren't the only party benefiting from sales as eBay and PayPal raked in a juicy profit of $625,665 as well."
Doing the quick math on some of the number the average profit on a scalped 5900x is around $240 USD
