RadioShack has been around for as long as I can remember. In fact, one of my first computers came from RadioShack. The electronics seller has all manner of stuff and back in the day, it was one of the go to locations for buying tech. As bigger electronics firms like Best Buy came around the need to go into RadioShack has waned for most of us.
The company is turning itself around though an attempting to bring more folks into stores by offering phone sales from just about every carrier there is. The latest device The Shack is offering is the Samsung Galaxy S. you can choose the smartphone from three different carriers. You can get the Samsung Epic for Sprint, the Vibrant for T-Mobile, and the Captivate for AT&T.
All three of those handsets share the exact same features, but have different extras. The Captivate on AT&T is the most expensive at $199.99 with a $20 instant credit for accessories. The best deal is probably the $149.99 T-Mobile Vibrant with a free copy of Avatar and The Sims 3 video game. Buy the Vibrant and you get a $50 RadioShack gift card by mail to boot. I guess there is nothing for Sprint, it probably can't afford any extras right now.
