It is in accordance to Ebay and Paypal dispute resolution that buyer pays for return shipping: 
"The buyer must return the item to you to qualify for a refund unless the buyer obtains manufacturer's or law enforcement certification that the item was in fact not authentic. In most cases, the buyer will pay for return shipping. 
Here are the criteria for return shipping: 
• Buyers must return the item using trackable shipping with delivery confirmation, or risk not qualifying for a refund if the item is lost in transit. (These are the same requirements imposed on sellers for item not received claims.) 
• If tracking or delivery confirmation is not provided by the buyer returning the item, and the item does not appear in a reasonable amount of time, then you are not obligated to refund the buyer."
