You can take your parcel to the Post Office, send it with parcelforce and pay the Post Office.
Sold items in 'orders' have 'add tracking' in the dropdown menu.
Lots of sellers buy their international postage directly from the carrier rather than buying through Ebay.
"There are two ways to be fooled. One is to believe what isn't true; the other is to refuse to believe what is true.”
Søren Kierkegaard, Danish philosopher (1813 - 1855)
