As a newbie on here I couldn't work out how the international postage rates work, bit thick in that department lol, anyhow when you put in a google search for postal zones europe the first page at the top gives you the europe zone (Royal Mail) which I copied and pasted into word, then clicked rest of the world which apparently is for the rest of the world as its says. I copied and pasted that under the countries of europe and the rest of the world gives you the rates for europe and the rest of the world then printed it so I just look it up on a simple piece of paper. Sorry to sound repetitive but it has so helped me work out the rates on site. For domestic rates just use the calculator on the royal mail site for the UK. The reason I'm excited about this is that I thought there would be tons of zones when in fact dare I say it there are just domestic and 2 other zones. Can I say thank you to Astral who pointed me in the right direction and who has been a huge help to me on here. I hope this can help someone out there the same as it helped me.
