Come August 1st, the United States Postal Service will no longer offer Saturday mail delivery. It's a cost-saving move that's been discussed for the past few years as the agency has struggled with massive losses — it was in $15.9 billion in the red last year — and it is now becoming a reality, according to multiple reports. News agencies report that the USPS will announce the change later today, and it's expected that it will save $2 billion per year. All mail activity on Saturdays will not cease, however: the quasi-governmental agency will continue to ship and deliver packages on Saturday (that remains a profitable part of its business), post offices will remain open, and P.O. Boxes will still receive mail.
