Amazon.com has the Tiffen 52mm UV Protection Filter for $6.99 with free shipping. This filter is sized to fit many lenses including the Nikon 18-55mm and 55-200mm models. The filter protects the lens from dust and scratching; you should have one for every lens you own. Other sizes are on sale as well, including 58mm for $5.99 (Canon 18-55), 67mm for $7.99 (Nikon 18-135 and 70-300 VR, Canon 17-85), and 72mm for $15.52 (Nikon 18-200 VR, Canon 28-135 IS).

Buy.com also has a 2-pack of Crucial 2gb Secure Digital Cards for $19.99 with free shipping, one of the best prices I've seen for a top-shelf brand.
