Believe it or not, this up-pricing of items is also popping up with retailers. Sites like Walmart.com have now started allowing third-party sellers to list sold-out items at higher prices. For example, the NES Classic video game system that sold out this Christmas. You can't buy it at WM.com for $59.99 because they are sold out, but they will allow a scalper to list it for whatever ridiculous priced they choose, and Walmart of course collects a fee for the listing. Same phenomenon.
