I think there are certain things that really need good clear descriptions - like clothing and collectables - but sometimes getting more info out of some sellers is like getting blood out of a stone.

I am definitely going to ask for more info when the seller has posted the listing via a mobile/iPhone/some-other-inadequate-piece-of-electronic-equipment, and a para notifying potential buyers of that fact actually accounts for half the text in the item description.

Thankfully, recently many sellers I've contacted have replied, but it would have been better if they had spent some time describing the item better in the first place so I wouldn't have to ask.  For those who didn't bother to reply....No Sale folks!
