Higher shipping fees will force e-retailers to adjust

Isaac Newton’s third law of motion teaches us that when one body exerts a force on another, the latter exerts a force equal in magnitude on the former. It’s a principle that has been strangely lacking in the logistics industry that has supported e-commerce sales and their gravity-defying growth. But not for much longer. Those who buy and sell goods online need to understand that the era of cheap and convenient deliveries is threatened by the continuously surging demand, which is clearly creating supply pressures and allowing operators such as UPS and FedEx to hike rates by 5% and introduce dimensional pricing.
