If you are in the States, right now New Egg has 16Gb of Corsair DDR3 1600 for $90, with a $30 rebate on top of that-look under the Black Friday banner on their webpage.  Just make sure your system can accomadate that much.

No affliation, other than I bought all the components of my current system there...
