Amazon will continue to take more B2C market share from X. The B2B market will follow. Now we will have 4 major providers competing for the same market, UPS, X, AMAZON, USPS. Amazon does not need X, the market will work this out. Competition will identify the most reliable and efficient delivery service with the Best customer experience.
Amazon became a household name in less than 10 years, and they are the pioneers of the unique service that others are trying to duplicate. The other concern for X is when will Walmart follow, and provide delivery themselves, they have the infrastructure and resources. Now that will be interesting.
