If you don't mind me asking, where did you find this deal? I see about $120.

i got Crucial 16GB RAM a while ago for $89...it was on sale.

Watch for sales :)

If you have a 2012 MBP (non Retina) you definitely will need the 1600Mhz SODIM chips.
 
I have a late 2011 MBP 15", sandy bridge - but it seems to also accept 16GB of 1600Mhz. I will probably take the plunge :p Hopefully Amazon will run a deal since I have a $20 loyalty credit on my account to spend.
