ВТОРОЕ ДЫХАНИЕ (SECOND WIND, not to be confused with my favourite drinking establishment) at the very beginning of Pyatnitskaya, Metro Novokuznetskaya, Tretyakovskaya. Specialize in expensive brands. You get about 30% of what it sells for. I’m very often in the area and can always help you in talking with the store keeper.
МЕЧТА (DREAM), Chistorprodny 9. Not quite so expensive brands, and their share is much more modest.
ВТОРАЯ ЖИЗНЬ (SECOND LIFE). Several stores. See http://dress-life.ru/
I only have experience with avito.ru. Not I actually but Alexandra with her ads that tend to grab just the right sort of response. I was surprised at how fast and easy things got sold or fount their new owners through avito.ru.

Please especially note Projects I know and support >>
I’ll be happy to help you interact with these, or to do a delivery
darudar.org if for giving things away for free or in exchange for something small but fun. Never used it. At a glance the system appears complicated.
otdamdarom.ru – Same as above but simpler. No personal experience but I heard people swearing by it.
The Orthodox Church has its own large and highly efficient collection system in Moscow, with distribution mostly in poorer regions. I interacted with it in the summer of 2010 during forest fires and was impressed. Since then from what I hear it continues developing quite successfully. Information on current distribution points is at www.diaconia.ru
