Newegg offers the Silicon Power S60 120GB Serial ATA 6Gb/s 2.5" Internal SSD, model no. SP120GBSS3S60S25, for $59.99 with free shipping. Outside of the deal below, that's the lowest total price we could find by $6, although we saw it for $15 less last month. It features read speeds of up to 550MB/s and write speeds of up to 500MB/s.
If you haven't yet, use Newegg's Android app and pay using Google Wallet to cut it further to $44.99, which ties it with last month's mention as the best price we've seen. (This discount can only be used once per account.)
