It you were looking for a good deal on the Samsung Galaxy S3 Amazon has some sweet nothings to whisper into your ear. They’re offering the summer-launched device for just $99 for those on Sprint, Verizon, and AT&T. Note that this is the 16GB version of the device for each carrier so think wisely before taking advantage. This offer is also available to new customers only — those looking to upgrade or add a line will need to add another $50 to that price. Verizon users will go here, Sprint users will go here, and AT&T users will mosey on over here.
