United States Postal Service at 328 East Wyomissing Avenue, Mohnton, Pennsylvania.

If you have a driveway, they do not deliver packages to your home. If it doesn't fit in your mailbox, they will not deliver. Do yourself a favor and get a huge mailbox with a large separate area for packages. Two years ago, a mail carrier placed one of my boxes in a trash can, presumably to shield it from rain, and it was taken away with our weekly trash (I know because she left a note) or stolen, never figured out which. It contained a Xmas present for my nephew. Kenhorst has an automated stamp dispenser and mailing device. Go there if you need to mail anything or get stamps after hours.
