Totally clueless here - hadn't even bought anything on eBay until a few weeks ago!
We've got a few things to sell, ranging from cheap children's books/clothes to a couple of valuable records and an exceedingly posh fountain pen.
What's best to do - auction or BIN? What about postage costs and packaging? I don't know anything about fees etc or even how to list things (will be using the iPhone app) 
Anyone want to advise a newbie? Thank you :)
