I have to mail a check so an envelop from the US to Canada. I cant find anywhere how many stamps I need. Anyone got a clue if it costs extra?
The UK's Royal Mail has a decent website where it tells us. Try your equivalent. Or if in doubt just whack $25 worth of stamps covering the entire envelope and you'll be sure it gets there.
Good thing you didn't take the advice above. That phone call saved you $24.27 if you had listened to the above.
