I purchased my ZIP Code database from http://ZipCodeWorld.com. Their basic version costs about $60. The thing is you aren't going to find them very cheaply (at least not legally) because they all are licensed from the U.S. Postal Service and they have to be updated on a regular basis by the vendors because new data is constantly being added as new street addresses/zip codes come into being.
