I need a German to English translation -- no online sites please (they make no sense)?

I sold an item on eBay, as I always do, but a German buyer is afraid of customs and stuff. Can anyone translate the following text for me to English?





Ich habe immer nur aus Deutschland was gekuaft.

Und ich mache sorgen wegen diese Sache, versenden sie es lieber nicht, weil dann werde ich wirklich am Arsch sein ^^

Wenn sie wollen k枚nnen sie sogar die ganze Summe behaten (ich habe damit keine Probleme)

Wenn ich zu Zollamt komme bekomme ich eine Anzeige von Polizei und das ist ganz schlecht.

The text has a lot of typos and informal grammar, so that's why a litteral tranlation won't make much sense.



'I have only bought stuff in Germany till now.'



'And I'm worried because of it now, it's better if you don't mail it to me, because then I would really be in trouble.'



'You can even keep the whole sum if you prefer (I don't have a problem with that.)



'When I would go to customs, I would get charged/notified/ by the police, and that would be bad.'
