So I tried to book it, got all through the form filling, getting the German address into the silly fixed but obligatory boxes was a struggle, then it won't accept the order without the recipient's mobile phone number, messaged him and got that ok.
Printed the labels off and parcelled it all up popped into the post office this morning, the clerk cannot send it because the system keeps telling him that the bar code is not valid.

There's a queue of ladies waiting behind me so I told him to put it aside serve the ladies and I'll call in later to see if he's managed to get it away.
