With a new 2-year service agreement, RadioShack offers the Samsung Galaxy S III 4G Android Smartphone for Sprint in Pebble Blue bundled with a $50 Google Play credit for $49.99 with free 2-day shipping and free activation. (This price is also valid on new lines added to an existing account.) Assuming you use the credit, it's the best deal we've ever seen for this phone. (We've listed it for $0 after rebate, however a $35 activation fee applied.) This CDMA 4G phone features a 4.8" 720x1280 Super AMOLED touchscreen, Snapdragon 1.5GHz dual-core processor, 2GB RAM, 16GB memory, 8-megapixel rear camera, 2-megapixel front camera, 1080p video capture, GPS, Bluetooth 4.0, 802.11n wireless, Samsung Galaxy S III Accessory Bundle, Google Android 4.0 OS (Ice Cream Sandwich), and more.

Update: Of note, you'll need to remove the extra phone automatically added to your cart during checkout.
