Chris says that you don't need a Macro or Wide Angle lens. There are plenty of ways to turn your current lenses into both.
1) Get an extension ring. It goes between the camera/lens increasing the distance. It reduces the minimum focal distance without affecting quality all that much. And you can get one with contacts to keep automatic functions.
2) You can also get a filter that acts as a magnifying flass. It needs to be "achromatic" to correct for color and distortion. But that's a good option as well.
