Amazon's added a whole lotta sweetener to its usual smartphone-for-a-penny pot. If your frugal heart's been holding out hope for a discounted drop of the high-end mobile goods, now would be the time to pounce. The Seattle-based web retailer's wireless arm is throwing every phone from Sprint, Verizon and AT&T under the $0.01 umbrella for a limited time. Starting today and running until the 28th, you can snatch up a Galaxy S II Skyrocket, Droid RAZR, Rezound or Focus S (just to name a few) for one Lincoln-embossed, copper-plated piece. But there's a catch, and you knew it was coming. In order to take advantage of this Crazy Eddie-like steal, you'll have to sign up for a new line of service. So, bust out the credit card (and your credit report), the mobile bargains lie in wait at the source.
