It's free, but it saves you money... it's like dating a girl whose way too hot for you and then finding out she loves Star Wars and has a Nexus One. I have saved literally hundreds of dollars with this while shopping at Best Buy and Walmart, both of whom price match. I saved $60 on my PC video card at Best Buy. I swear by this app and can't understand someone not getting it. Maybe if you hate money than this isn't for you. Otherwise, its quick, simple interface is something that you shouldn't be without. No battery drains, frequent and quick updates and no training required, this one should be on every Android device, rooted or un rooted.
