LOL. my mother works for Canada Post. The bulk of the fee to deliver a parcel goes to pay for the gas yet they charge an extra charge now on top of the shipping charge as a kind of gas tax.
This gas tax is supposed to go to the mail delivery people to help against the rising fuel costs because for most of the rural delivery people they have to pay for their own gas and get re-imbursed for it on their paycheques. I talked with the guy who delivers the mail to my house and he hasn't seen a single extra penny apparently. He even has to use his own truck because Canada Post won't supply him with one of theirs.
Strangely enough, during the same time period at our local postoffice, the head guy who runs the place decided he was going to retire early as he received a nice $200,000 performance bonus or something like that.
I will admit though that the speed of delivery has improved, in our area at least anyway.
Canada Post, baby! They charge you twice as much for the privilege of never seeing your parcels again!
