A4C offers the refurbished Skullcandy Supreme Sound Riff Headset in four colors, model no. S2RFDA, for $4.95 with free shipping. That's $2 under our May mention of a refurb and the lowest total price we've seen for this model. (It's also $8 below the best deal we could find for a new set.) Features include in-line controls, built-in mic, and replaceable silicone gel tips. Deal ends September 22.

Note: A 90-day A4C warranty applies.
