Canada to Overseas (incl. UK) rate is CAD 2.50 for a small envelope up to 30 g. and it is CAD 5.90 for a large envelope up to 30g. In Canada, there's no more economy service offered and everything is going airmail (priority). Also, it is important to know that permanent (domestic rate) stamps (P in a maple leaf) are sold in booklet and rolls for 0.85 each, but you cannot get them separately. If you want singles, they're sold at 1.00 each. Otherwise, look for CAD 2.50 overseas stamps or multiple CAD 1.20 + 0.10 stamps (to make up to 2.50/5.90). Expect sales taxes (and s&h) too.
I have weighed it on kitchen scales hence the 3oz max. Just cross checking the cost of a 3oz max C5 letter from Canada. Additionally, the Canadian stamps, can I use any types as long as the value reaches the postage cost?
Ok... looking at it... it's going to cost me $5.90 (Canadian Dollars) on the SAE. Silly question but can I mix and match for international mail ... example is
Baby Wildlife: International Stamps ($2.50) - Booklet of 6
Queen Elizabeth II: Booklet of 10 ($0.63 Denomination)
So would use 2x baby wildlife and 2x Queen Elizabeth. Making it $6.26 ??
This is so I can make up the difference rather than using 3 international stamps at $2.50 each.
