I think we have something similar in France but I'm not sure. I remember that the one time I actually needed to send letters which I have pre-stamped, was when I was sending applications to universities. Fun thing happened though, as the postage has increased _the day after_ I've bought and stamped my envelopes. So then when coming to post office I needed to buy something like three 2cent stamps.
