So, for a couple months, I worked for the Government of Manitoba. Of course, there is Inter-Departmental Mail, which re-uses envelopes. The envelopes easily make it all the way through the province. Once I was finished my term there, I needed to get some things from HR. They sent it through Inter-Departmental Mail, and all I can say is that I feel semi-important because I got an envelope that was used by the Premier himself! (Or his secretary…same difference!) Check it out…1 to 5!
