That's pretty darn cheap. On today's Gold Box deal, Amazon has chopped an extra 30 bucks from its refurbished Kindle Fire stock The retailer promises that all the tablets are certified to "look and work like new." At the time of writing, tablet hunters had an extra 18 hours to stake their claim, but the sale will stop once it's sold its stock. There's also a limit to five per customer -- a warning to all those auction-based-get-rich-quick schemers.
