This deal has ended.
Buy.com has the Logitech Quickcam for Notebooks Pro for $29.77 after a $30 mail-in rebate currently valid through 7/22. This is $70-$100 at other stores and one of the best deals I've seen on a webcam with 1280 x 1024 resolution (1.3 megapixels). This is a well-reviewed, high-end webcam that includes a built-in microphone. Shipping is free and there is no sales tax (except CA, MA, MD, TN). New Buy.com customers can use this $5 off $50 coupon and new Google Checkout users can get a $10 off discount for signing up (you can't get both).
