First, my apologies for the absence and thank-you for reading.
In this depression consumers are pulling back on the "extra." One example is the speed of items shipped. Many online ordering services offer a discounted, often free, shipping option which takes the most amount if time to arrive. This most modest option often employs the US Postal Service in the United States.
It would be interesting to know how the percent of online derived business for private porters has been effected. Likewise, how has the US Postal Services position as "shipper of last resort" effected the national revenue at a time of financial austerity.
