Now, just like there's no business that can survive losing 30% of its sales overnight, there's also no business that can afford to hand 45-51% of its gross margin to a retailer. For businesses to survive at all on Amazon, they have to jack their prices up - *way* up. However, Amazon has an anticompetitive deal called "most favoured nation status" that forces suppliers to sell their goods on Amazon at the same price as they sell them elsewhere (even from their own stores).
