Don't bother selling your stuff this way. You will always end up dealing with the cheapest *bleep*piest courier.

I sold an item which was broken by the courier in transit. Ebay state they will be responsible for dealing with goods damaged in transit under terms of "simple delivery" 

This is nonsense - what they actually do is simply return the  broken stuff to you and charge you a refund to the seller.  Next time I sell it won't be on Ebay
