Newegg offers the Ematic Portable Bluetooth Speaker with 8-in-1 Universal Accessory Kit, model no. EP205, for $9.99 with free shipping. That's tied with our mention from Black Friday week as the lowest total price we've seen. (It's also a current low by $7.) It features a miniUSB cable, wall charger, car charger, cleaning cloth, carrying pouch, aux cable, and an audio splitter.
Orders placed by December 19 at 12 pm local time are guaranteed to arrive in time for Christmas.
