Lao A. (eBay Customer Service):

 "I am afraid the best offer is only for the item not for the postage charge, you need to pay for postage charged differently".

And eBay wonders why it is their customers have trouble believing that 'free postage' is actually 'free' ?? When their own employees are struggling with the concept of 'free postage' what hope do their customers have of coming to terms with it ?
