Where can I donate/get rid of old clothes? - Berlin

I'm leaving Berlin in a hurry and in the inevitable purging of stuff I'm not taking with me I now have a fat sack full of old clothes that are too good to throw out but that I don't use anymore.

I haven't seen any of those clothes drop off bins in Berlin and I don't know of any pick up service. Does anyone know of a place I can leave them? It would be a shame to just throw them out as they are all still very wearable and I'm sure someone would appreciate them. Do second hand shops just take stuff over the counter? I don't want any money for them or anything, just a good home.

Also, I live in Friedrichshain and don't really have time to travel all over the city this week, so local suggestions would be doubly helpful

Here's one place to try:

caritas

Lausitzer Straße 41-44
10999 Berlin-Kreuzberg
Telefon: (0 30) 6 66 33-3 90
Fax: (0 30) 6 66 33-3 94
l.kalender@caritas-berlin.de
