Get 4GB desktop RAM for just $19.99 shipped! This is 2GB x 2 (DIMM, DDR2 PC2-6400, DR2-800). Note that a 32-bit OS maxes out at 4GB of total memory. Something like this easily goes for $50 or much more at most places (It’s over $200 at BestBuy!). Getting it for $19.99 shipped after a $35 rebate is just a great deal.
