Where can i find a map showing the zip code areas in my state?

[coolred]

I know they have them, I have found them for sale online, but I don't really want to pay for it. I thought maybe the phone book might show them, but it only shows the area codes. I am sure there is probablly a site somewhere that has them for free, but I have yet to find it in my searching, so if you can help me out, please do, thanks.
