I just upgraded the RAM on my Macbook Pro (Early 2011) from 8BG to 16GB, and then, using the 8GB that used to be in my machine, I in turn upgraded my wife's computer, also a Macbook Pro (Early 2011) from 4GB to 8GB.
So, I now have the extra RAM, and I'm willing to donate to someone who would can and would like to upgrade (and will use it). Please note, not all Mac/Macbook RAM is the same. The RAM I have is 2 x 204-pin SODIMM 1333 Mhz DDR3, with RAM specifications of 9-9-9-24.
BM me if you're interested (I live in Utah County).
