6pm offers the Skullcandy Icon 2 On-Ear Headphones with Microphone in Lurker Green/Black for $13 with free shipping. That's the lowest total price we could find by $7, although we saw them for $1 less last week (since expired). They feature a 3.5mm gold-plated connector, 30mm drivers, frequency response of 18Hz to 20kHz, in-line microphone, and more.
