usually they ask yo uto ship it back anyway as you could be usign a friends receipt or a friends sireal code, not everyoen is as nieve as lg, i got my second monitor for free as they sent me the new one but the tech forgot to ask for my credit card number as colateral incase i didnt send the old one back, so i never sent it back, turned out my 7900gt was artifacting my desktop and it wasnt the monitor dying.
