Amazon offers the ContourROAM 1600 1080p Waterproof Hands-Free HD Digital Camcorder for $199. Coupon code "89ROAM89" cuts it to $89. With free 1-day shipping, that's $30 under our mention from eight days ago and the lowest total price we could find by $110. (It's also the least expensive waterproof 1080p "helmetcam" we've seen.) It's fully waterproof (up to 1 meter) and features 1080p recording, 5-megapixel still photos, microSDHC card slot, USB connectivity, and more.

Orders placed by December 22 at 7:30 pm ET are guaranteed to arrive by Christmas.
