The Galaxy S III, one of the best phones on the market, is on a big sale right now for three of the major carriers. Amazon Wireless is selling the Verizon and Sprint models for only $99.99 to new customers (and $149.99 for upgrades, sorry guys). The AT&T model is a bit pricier at $129.99, but upgrades are a cheaper $139.99. Either way, it’s a great deal for a great phone. If you want it, hit the source link for your respective carrier!
