The desperate U.S. Postal Service’s plan to cut mail on Saturdays (but keep package, priority, and express delivery) is not good enough for Congress, which has final approval over the agency’s budget and apparently wants its weekend Sharper Image catalogues. “The board believes that Congress has left it with no choice but to delay this implementation at this time,” said the USPS today. “The board also wants to ensure that customers of the Postal Service are not unduly burdened by ongoing uncertainties and are able to adjust their business plans accordingly.” Considering the Postal Service lost almost $16 billion last year, its own business plans remain a concern, too, and a five-day schedule is not being ruled out competely. The question is whether paper goes extinct first.
