This is a cool idea, good luck with it all!
I've got plenty of stuff to sell, but like others have mentioned, it's often a lot of effort to list these things and by the time you take into account postage and the eBay cut or whatever, it's barely worth it.
Definitely a cool idea though, seems like your doing really well so far. I bet it's quite fun in a way trying to find a bargain.
