The monkey house is having a clear out and second hand is a very hard sell. Carpet (unused low meters) is unwanted and when people think there is a value to now unwanted stuff finding a market for it is hard.
Granted some things do sell but there more upper class items rather than lower class things. There are also fees for selling if you use the wrong sites so its an impressive feat to sell good stuff but it is a lot of work and not much profit for the effort.
Charity shops (my blog) dont help either
