I had something unusal happen the other day. My cell phone service provider called and gave me a tip for how to save some money. His tip: Rather than dial 411 on my cell phone which costs $1.79 per call, try Google's new 411 service. Its free! Just dial 1-800-GOOG-411. Thanks AT&T.
Note, I called this number and the service is for businesses only, not personal residences.
