I've been playing the Marketplace tango all day today myself! Gosh, what I would do for a naturestrip outside my place so I could just unload stuff that won't move.
It is definitely frustrating. Some people don't seem to have the skills to be able to organise a time to get things. I'm not sure if it is a communication issue or an inability to commit to anything in advance but I've had a few people that seem interested but just don't seem to be able to make a time.
