IDK if this is a special promotion or not, but you can order a 16gb kit off amazon from Komputerbay for $140. http://www.amazon.com/gp/product/B00698WP50/ref=oh_o01_s00_i00_details After reading the forums and other amazon.com reviews it appeared that they are a kinda hit and miss company in terms of sending you bad ram. But amazon has free returns and exchanges so I figured on the off chance I got bad ram I'd just keep returning it until I got a pair that worked. For less then half the price of OWC It would def be worth the hassle so I took a chance. It came several days early, I put it in my early 2011 core i5 MBPRO, and immediately ran memtest in single user mode. It took a couple hours to finish but the memory checked out fine. Since then I haven't had any problems. In fact the only hassle I had was finding the #00 screwdriver that I needed to take the bottom of the MBPRO. My computer has had a huge speed boost and I haven't seen a spinning beach ball since I upgraded. Also, for all those on here that say why get 16gb when 8gb will do I say that may be true right now, but in another year or two that will not be the case. Remember only a few years ago more then 4gb on a laptop was considered overkill. I see it as a way of futureproofing. Oh yeah i'm running 10.7.2 Lion.
