Fry's Electronics offers the SanDisk Extreme II 120GB Serial ATA 6Gb/s Internal SSD, model no. SDSSDXP-120G-G25, for $75 with free shipping. Outside of the below mention, that's the lowest total price we could find by $5, although we saw it for $5 less last week. It features write speeds of 340MB/s and read speeds of 550MB/s. Deal ends October 2.
A close price: Newegg has it for a penny less plus $1 shipping.
