RadioShack always has some nice deals going on, and if you were planning to buy a Samsung Galaxy S 4, RadioShack might be a good place. They currently have a deal that, if you buy more than $30 worth of products, you’ll get a $10 off coupon for a future purchase. Since the Galaxy S 4 is worth more than $30, you’ll be getting that coupon. And if that isn’t enough, you can also use their trade in policy, if it applies to you. It might drop the price of your new device pretty significantly. So, if you’re going to get one, consider heading to RadioShack this Saturday, the 27th.
