Agree - the weirdest thing is getting 'is this available?' question and when you say 'yes', they don't respond, what is that about?? Was selling Le Creuset pouring saucepan, little used and in excellent condition (moving house I had a glass top cooker, so not suitable). Constantly received that query, but not one person followed up, sold elsewhere for a higher asking price plus postage costs!
I have only used it when I have items I'd rather not put in the post - but none of them have sold - and didn't realise, until recently, that if you relist the item it is not put at the front of the queue, it just stays at the end!! Seems to be a waste of space.
