Fry's Electronics offers the Swann 720p HD ThumbCam Mini Video Camera, model no. SWVID-THUMBC-GL, for $54.99. This $30 mail-in rebate drops it to $24.99. With free shipping, that's the lowest total price we could find by $45 and the best price we've seen for a mini HD camera. It features 1280x720 video recording at 30 fps, 1600x1200 still images, built-in battery, and USB. Rebate ends December 26.
If you want it by Christmas, opt for in-store pickup by 3 pm local time on December 24. (You can also select expedited shipping, which tacks on at least $14.)
