Walmart offers the Ematic Portable Bluetooth Speaker with 8-in-1 Universal Accessory Kit, model no. EP205, for $12.88. (iOneBay via Amazon charges about the same with free shipping for Prime members.) Opt for in-store pickup to avoid the $5.97 shipping fee. That's tied with our July mention (although that included free shipping) and the lowest price we could find now by $12. The speaker features Bluetooth with a 30-foot range, a built-in microphone, auxiliary port, microSD card slot, and rechargeable battery with up to eight hours of play-time per charge. The accessory kit includes a wall charger, car charger, mini USB cable, aux cable, audio splitter, cleaning cloth, and carrying pouch.
