Tanga offers the Bios Bullet Cam 3.0 Waterproof Action Camera with Accessory Bundle for $11.99 with free shipping. That's tied with our mention from a week ago, $38 off, and the lowest price we've seen. It's waterproof up to 10 feet and features 640x480 video recording at 30fps, a 1.3-megapixel still image resolution, microphone, microSD card slot, and rechargeable Li-ion battery. The accessory bundle includes multiple mounting options, USB and AV cables, and a charger.
