This idea has been floated before. Considering Amazons lack of profit generation, what makes you think they could buy UPS?Amazon has the money to buy UPS. Amazon has zero experience with union workers so they would be very reluctant. Amazon isn't disgruntled with UPS they don't like the grip the union has on the company. Since FEDX express and ground mirror rate increases with UPS the key to lower shipping cost (the heart soul and core of Amazons business model) is to break UPS unionized workers.
