A long time ago Amazon tried to acquire a good online business diapers.com and initially the owners refused. Amazon proceded to get investors or lenders to funds 200 million dollars to undercut sales of diapers.com. Fast forward they were close to bankruptcy and owners were forced to sell it off for a bargain to Amazon. Since then the price of diapers have risen to be very profitable.
