Perhaps I could have been clearer. > Who adds these items to increase weight? Private delivery companies add these items. > Why? Because due to the existing PMMS (Poczta Polska to be exact) monopoly on mail <50g, private companies would have to charge 2.5x the PMMS rate to deliver the same piece of mail. Adding the item allows a private company to circumvent the monopoly (by increasing weight >50g) and thus being able to deliver this piece of mail at a lower rate than PMMS. How this ends up being profitable is a bit of a mystery. > If PMMS is adding this weight They're not. They have the monopoly so they don't need to. > they're wasting fuel delivering light items. No arguing there... This is what one of those metal plates looks like http://gfx.mmka.pl/newsph/222924/44881.3.jpg http://gfx.mmka.pl/newsph/222924/44881.3.jpg
