I was poking around the contract and came across some interesting findings regarding surepost. There are clear cut guidelines regarding surepost restrictions. The first & most obvious is that packages must be less than ten pounds. Next, the contract states that packages cannot exceed three cubic feet. The formula to figure the cubic feet of a package is the following: Length x width x height. Three cubic feet=5184. Anything exceeding that is in violation. The final and most obvious violation that I found is that surepost is to be offered from a commercial address to a residential address. In other words, no surepost to businesses. ANY & ALL SUREPOST PACKAGES MUST BE RESIDENTIAL....NO BUSINESSES!!!
