Since I did not have a PayPal Account before, I have just now registered one. PayPal still awaits confirmation of my Bank Account, so that might take 2 to 4 days (as they claim). I hope that thereafter I can quickly transfer the payment to you.
If that takes too long, I would second keymonger and ask you to email me your details as well. Alternatively I can suggest we meet somewhere in between Heidelberg and Dortmund and I hand the money over to you cold-war style, preferably on a bridge.
