USPS to Deliver Packages 7 Days a Week This Holiday Season

"The Postal Service will be out making deliveries every single day during the holiday season, including Christmas Day," said Postmaster General Patrick Donahoe in the press release.

Due to continued e-commerce growth — and improvements to its Priority Mail product line, according to the release — the USPS is expecting double-digit growth in its package business this holiday season, likely in the range of 450 million to 470 million packages. That equates to 12 percent growth over the same period last year.
