United States consumers have benefitted greatly from reduced oil prices, allowing individuals to fill their gas tanks for cheap and heat their homes in cold winter months. Companies, too, benefit from these sharp declines, however, they are often not the most obvious. Last year, Amazon (NASDAQ: AMZN) spent almost $8.7 billion in shipping, according to Yahoo Finance, accounting for more than 9.8 percent of the company’s revenue. However, with reduced oil prices, the cost of shipping is likely to decline, ultimately reducing its net shipping costs.
