If you’re in the market for the highly anticipated Samsung Galaxy S 4, you might want to check out Radio Shack. They will have both Sprint and AT&T’s version up for sale on April 27th. And if you purchase the device from Radio Shack it comes with free mobile product support from one of their stores, live web chat and other online services. You could also trade-in one of your old handsets for up $300 towards the device. And to add icing on top, if you spend $30 or more on accessories you’ll receive a free $10 for a future accessory purchase. Those are some pretty sweet deals and it’s worth the trip to Radio Shack.
