The U.S. Postal Service (USPS) has strictly instructed people not to use their Blue Boxes.
This usage restriction is only for limited days
The USPS says If any one uses these boxes on Sundays or on Holidays Chances of Theft are high
The post is suggesting people to visit the local post office or put mail in boxed after last dispatch
With Blue Boxes the USPS has to bear high expenses
As the Blue Box requires transport to pickup the mail twice a day
With increasing numbers of theft and also it includes lot of expenses to USPS
Soon USPS could discontinue the blue boxes
