Megacharge; people are free to ask any price they like for their items. No one is accidentally going to pay $190.00 for a $40.00 item. In this case it was a mistake.
Best Buy wants $69.99 for the charger when you can get it on eBay for $40.00. Have you reported Best Buy?
Of course it was clearly a mistake. I was speaking generaly. People are free to ask whatever they wish unless it's a con in someway. If you see somebody doing fraud - report it, if you see somebody trying to get some profit and you dont like the price just move on (again generaly and not about this very case).
