Anyone ever try this? It seems to me like you could enter the athlete's address as the starting address, your own address as the destination, print the label and put it on your SASE and mail it, thus negating the need for people in the US from buying Canadian stamps.

Just a thought. As an aside, if this doesn't work, I need Canadian stamps.
