Ebay prices are allways outrageous... Sell it on ebay if you want that much. Just don't come crying when someone bricks it or scams you and then wants a refund which you are obligated to give them due to the 45 day no questions asked warranty you give on every item you sell. 
Where did you get that? Any sources?
It's not that easy. If you can proof that you sent the item and the customer received it it isn't possible. Otherwise I'd be able to screw over whole eBay on a few millions.
For digital goods it's something different though.
Unfortunately it is that easy. Buyer simply files for item significantly not as described, claims it is defective (lies if need be) and ebay sides with the almost without fail. This forces you to accept the return AND dings your ability to have future listings even show up in searches.
