Now that the Samsung Galaxy S4 is announced and ready to head to stores, the flood of Galaxy S3 price drops have begun with RadioShack and Sprint. For new customers signing a 2-year contract, the Galaxy S3 has dropped down to just $49.99 from its original on-contract price of $199.99. If you bring in an old device to trade in with the "Trade & Save" program, you could get that down to $0 quite easily as well. As is usually the case, line upgrades will be charged a $50 premium over new sign-ups.
Now the smart money would say that you should wait for the Galaxy S4 to hit your carrier of choice before you make your decision. But if you're in dire need of a new phone and don't want to break the bank, be on the look out for these price drops.
