The US Postal Service is doing fine job with packages, and they have improved greatly over the years...Corporations are stupid if using FedX or UPS for small packages, but who cares with them, the stock holder pays for it or their consumer, but still money that could have been more profits for the stock holder...
Though very large corporations get a discount with FedX and UPS...so maybe they can get better prices than I could as a very small business?
Lower gasoline prices is going to help all three of these businesses, especially the postal service who does not have a gasoline/service charge when gasoline prices go up.
There is room for all 3 package services....it helps keep all 3 competitive and the more competition the more cost effective conscious, all three of them become....
