Photogs, graphic artists-are you using PNG?

Compare PNGs from Photoshop saved via Save as... vs Save for web and you'll see a difference (at least in file size.)

Just FYI, the file size disparity is also true of JPEG. The reason for this is that the web exported versions don't include the file metadata that is included in a traditional save.
That's not quite accurate. There's a lot more going on, it's not just metadata. For example, many colors are stripped out as well.
