If we did try to merge and usurp amazon and other etailers. Don't you think that amazon, along with other ecommerce companies would leave UPS? Amazon, staples, walmart, target, qvc, hsn, etc wouldn't want to do business with their competitor. That would be a huge boon for the USPS and FDX as well as couriers. Would they be able to handle all the volume right away? No.. But i do believe they would divert and keep diverting so long as we were a competitor. Also, why would we want to get into that business? As it is, amazon doesn't really make much profit on their online sales.
