The holiday season is here and deals are popping up all over for computer hardware. This is a breif summary of the lowest prices I've seen on a few SSD's including mail in rebates ($20-$30) and shipping. I had been watching prices on these SSD's since June of this year before I recently purchased my first SSD. With this, you can know if the deal is good or if you should hold off for a better one.
