I wanted tracking because Canada Post has lost a few things sent to me. I guess I just have to try to trust them with regular lettermail.
It's just so crazy to me. I have family overseas that ships boxes to me regularly and it costs no more than (after exchange rate) $10. To send a box across the ocean. But to send an envelope a few hours away costs more? I just... I really can't even begin to comprehend this.
I know retailers that send a lot of stuff out get special rates. But I assume there would be this huge gap for them too to use envelopes instead of boxes.
I don't know that it's any cheaper for you, but in one of the weird Canada Post conundrums, sending something via XPresspost is frequently no more expensive than sending it via "regular" mail, and that service includes traffic.
