Very inefficient. I tried to track my package and it showed that it was delivered to my local post office (2 miles away) but it would be another 4 days before it would reach my home. So I went to the local post office to pick it up and they said that I would just have to wait till it was delivered. Sounds like an inefficient system. If I simply mailed a letter within my local area, it would reach in a day or two. How in the world does a package sit in a post office for 3 days before they send it out for delivery??
