Cell Phones : Amazon.com

This may be extremely obvious, but amazon is close to the cheapest place to get a phone. Of course, you have to wait for shipping, but if you don't need the phone right away, amazon is quite a bit cheaper than most stores you can go to. I bought this Motorola Q phone for $50, plus a $100 rebate, so in all it was $-50 with only a one-year contract. You should check it out, they carry all the major carriers and I think they have more free phones than any other site I've seen, most with no (or cheap) activation and only one year contracts.
