Dropshipping windows software

I been looking into dropshipping copies of windows7 with genuine keys from dhgate to my ebay customers. Problem is, although the keys are legit, the physical discs themselves are copies... REALLY GOOD copies. Anyone had any success/failures with it so far?

i used to offer Windows 7 as a free download if they bought the legit key from me. I had alot of buyers for this with ZERO complaints. you should try it also
