MegoShop2012 via eBay offers this Lighter Spy Camcorder for $5.06 with free shipping. That's a slight drop since our mention from last week and the lowest total price we've seen. (It's also a current low by $6.) It features a 720x480 video resolution, built-in microphone, rechargeable lithium battery, and USB.
Note: This item ships from Hong Kong and is expected to arrive in three to eight weeks.
