Procurement spending by the U.S. Postal Service declined slightly in 2011, but capital spending was anemic, according to the agency’s recently released Form 10-K report. Capital expenditures experienced a 15% drop from 2010 levels. This comes on top of a 24% decline in capital spending a year ago.  Transportation spending was once again the leading procurement category, totaling $6,389 million — an increase of $511 million, or 8.7%, compared to 2010.  More expensive fuel accounted for much of this increase, as diesel fuel prices rose 26.6% from a year ago.
