They're cheaper on Amazon. For example, the Nikon D3100 that sells for $589 in camera shops is selling new for $529 on Amazon. Is there any drawback to buying from Amazon instead of a camera shop?

I own a Nikon D80 and am planning to invest in another lens sometime soon.
Right now, I have an 18-135mm, a 50mm, and a 28-300mm. Any suggestions as to what I should consider next? Thanks!
Added (1). The lenses I have right now do overlap. The 50mm was a gift. The 28-300mm was inherited. The 18-135mm came with my camera. I'm looking for one that will do something that mine can't.

I'm interested in learning about photography. What camera should I start with?
I'm going to school in January for photography. I'm planning on becoming a wedding photographer at the end of the program.
I have been doing a lot of research on cameras and I have narrowed it down to three choices. I'm considering the Canon Rebel T3i, the Nikon D5100 and the D7000.

Looking for a good online learning tool for DSLR cameras
I've had a Nikon D5000 for about a year and am still not getting the results I want. Does anybody have any good websites/books/ebooks/etc that will help a beginner. I do not need to learn how to "photograph" I got into photography because I have been told I have a good eye for a great picture. I'm just having trouble with te technical features of the camera itself.
