  Bottom line, you need to make real money someplace. You can use that to subsidize other parts of your business, but you can't use low-margin divisions to subsidize no-margin divisions. That's basically what Amazon is doing. It's why they have a PE of 000. They're growing revenues but not profits, so I have no clue why investors keep rewarding them. There's no possibly way Amazon will ever grow profits to match that PE based on anything they're showing us now.
