RadioShack slashes prices on Galaxy S3, iPhone 5 and 4S

With Samsung's Galaxy S4 unveiled last week and rumors of an iPhone 5S on the way, RadioShack is letting loose some of its inventory at a discounted price.

The consumer electronics store is offering deals on the Samsung Galaxy S3, iPhone 5, and iPhone 4S to Sprint customers starting today. A RadioShack spokesperson told CNET that this sale will last between now and April 4.

Of the three devices, the best deal seems to be for the Galaxy S3. With a new two-year contract, customers can save $150 on the device. Typically the mobile phone costs $199.99 at RadioShack, but the company is now offering it for $49.99 with a new Sprint account.

For the iPhone 5 and iPhone 4S, customers can save $50 on the smartphones with a new Sprint plan. The promotion is in-store only, so customers can't score the lower price by ordering online.

For those people looking to save even more money, they can use RadioShack's "Trade & Save" program, which lets people trade in their old devices for cash toward their new purchase.

While RadioShack is one of the first stores to start giving discounts on these top-of-the-line devices, it's likely other retailers will start offering deals on these smartphones in the near future too.
