I don’t get it.
It now costs 52 cents to send a letter within Canada. Oh, actually, make that a STANDARD letter. Fancy square envelopes cost more. How much? $1.10. So, let’s say you have a full roll of 52-cent stamps (or P for Permanent), and you want to mail out a batch of Fancy Square Wedding Invitations. You need to put two P stamps, and three, two-cent stamps on each.
Well, what about a square letter going to Australia? $1.55.
And a square letter going to the US? 93 cents.
