Monopoly for Millenials, an edition of the game noted for its surprisingly contemptuous mockery of younger generations, was perfectly-designed to go viral. It's $55 at Amazon, but WalMart had it for just $20 (sold out, I'm afraid). This guy went from store to store buying every box and selling them online. All he had to do was iterate the "available" count on a single listing, raking in $2500 in a single day's work.
