I'm looking to send a parcel of a couple of books to North America, how would I go about doing this? Can I just show up to my local post office and send it off? What kind of stamp do I need? What do I even write on the box?
The whole process confuses me, I haven't posted a lot of things in my life and I'm worried I'll get something wrong and the parcel will get lost.
Any help or advice would be hugely appreciated!
