Click2Mail: A service that lets you upload a file to be sent via snail mail

Sometimes you want to send a message via snail mail and don't want to walk to the nearest letter box to drop it off. Click2Mail lets you upload a file (such as a pdf) and they will print it and mail it with a stamp. This is great if, for example, you are affected by the current Canada Post strike and want to send some documents to the U.S. Or you have a 75-page document to send and don't have enough paper or ink.

I have used this to send some documents (and scans of handwritten letters) to my aunt in the U.S. during the Canada Post strike.
