Just a heads up guys... Don't count on selling your memory back to OWC if you buy from them. I bought some memory from them and they sent me an RMA to buy back my Apple memory. Three weeks later I got a check for almost 40% less than the memory was when I sent it in. No email, no confirmation, no heads-up, nothing. When I called them and asked them to send me my memory back they said it had already been assimilated and I was out of luck. WTF OWC?? I expected more from them... So, anyway buy from them if the price is right, just don't count on selling them your stuff. I would have been happier if I had just kept my old memory in a dusty drawer for a year or given them away.
