Did you miss late March's $139 Amazon Gold Box Deal on the refurbed Kindle Fire? Well, the retailer is giving you another chance, bringing back the deal for today (May 5th). It's the same discount as the last go-around -- namely, $30 off the standard price for the refurbished Fire -- and Amazon still certifies and reseals it. It's even throwing in a one-year warranty for good measure. Also like last time around, there's a limit of five discounted Fires per customer, so don't get too grabby.
