If we did NOT have sure post we would have more driving positions, we had all the sure post volume before giving it to usps. Do you have any idea how many people stop me a week and say "it shows my pkg was delivered today at the post office, why is that?" Keep in mind, Im in front of their house and the package they are referring to I dropped off at the post office 3 hours prior.... How do I explain to them that they will get it tomorrow? All the little boxes of contact lenses, coffee, and small amazon packages I drop off at the PO. Yesterday, I delivered 77 pieces to the post office...keep in mind that the BAG of smalls counts as 1 piece, I had roughly 60pkgs, and 17 bags(with 10boxes in each) thats 230 small boxes, enough to create another route "for that particular loop".
