Prices slashed on new Apple (AAPL) iPhone 5C

Walmart, Radio Shack, Best Buy cut prices

The phone was just released last month, but three big-box retailers have slashed prices on the Apple iPhone 5C.

Radio Shack and Best Buy announced they would be selling the phone under contract for $50, half off the list price, by including a $50 gift card with purchase.

Not to be outdone, Walmart then dropped its price to $45, down from its previous price of $79.

The deals are good for those who agree to a 2-year extension or new contract with AT&T, Verizon and Sprint.
