Costco is selling the Logitech C615 HD Webcam (Costco item number 610785) at closeout for $44.99 which is $5 off their regular $49.99 price. This offers lasts through February 27, 2012, but isn’t available online, so you’ll have to visit your local Costco to see if they have any left. The store I visited still had about a dozen on their shelves.

Take a look at the reviews at Amazon to see how it rates compared to other webcams. Amazon’s pricing as of this writing is $10 higher but does include free shipping.
