Where can I find cheap nikon D3000 lenses?

I'm looking for a site that sells cheap lenses for the nikon D3000 something like tamron or another lens brand that makes lenses compatible with the nikon D3000. Also if they come in a kit with different lenses would be a plus

Amazon and Fumfie.com. Also you can try b&h photo and video.

Actually I saw a D3000 on line yesterday for $650… Same price as always. Just because it's an older model doesn't mean it sells for less.

The Nikon AF-S Nikkor 50mm F/1.8 G lens offers a solid feel, and incorporates an AF-S type auto focus motor providing full AF compatibility with all Nikon digital SLR camera's and quieter and faster focusing. Although it is not as rugged as some of the higher-end lenses in the Nikkor lens line up, the Nikon AF-S 50mm f/1.8 G is a well built lens considering the fairly reasonable price point.
