The service's 12,000 vending machines will be eliminated nationwide Aug. 4, victims of obsolescence and cost-cutting.
"Most of these machines were 20 years old," Frances Sansone, a Postal Service spokeswoman, told The Daily Press of Newport News, Va.
And most customers using the machines usually buy just single stamps nowadays, she said
"We're not taking in enough money to work the machines," Sansone said.
By removing the machines, the Postal Service expects to save at least $66 million on expenses, maintenance, parts and labor.
