DailySale offers this Earbud Headphones with Mic 3-Pack for $5 with free shipping. (Outlet-Malls via eBay sells them for slightly more.) That's tied with our mention from two weeks ago and the lowest total price we could find by $10. They feature a clickable mic for taking calls.

Note: The countdown timer on the product page does not reflect an actual expiration time and resets daily.
