Hello @Mirella673
What a WONDERFUL idea to study in !
We would to have you here.
You asked about postcards in our Country. Here is a start:
Any Post Office would be more than willing to help explain the cost of our stamps to Canada, the USA or overseas (International)
I’ve discovered there are postcards with pre-paid stamps on them you can order online. You are getting a FREE postcard and just paying for the stamp. Yesterday I ordered two sets of our FROM FAR & WIDE and there was no cost for shipping!
You will be surprised at how easy it is to be a Postcrosser in Canada, eh?
