What is the most affordable way to buy an iPhone 5s?

I really want a new phone but I don't know how to go about it. I want an iPhone 5s, but I can't afford full price. I've seen websites that make you pay $15 a month or so, but I don't know if that's the smart way to go at it. How should I go at it?

Is it time to take Marquette off my college list?

I have a 3.5 uw 3.7 w. My ACT was only a 26, so I started to get worried. I live in Illinois. I toured Marquette. It was a pretty campus, Milwaukee is a gorgeous city, but the crime rate is awful. There are robberies outside the dorms every night. It's hard to have a normal night life in Marquette, especially in that area because of how bad the crime rate is. My cousin transferred out and said a kid got shot in the hand for his iphone.

I got my sat results back. I got a 1960 equivalent from the old one. Is it time to say goodbye, lol?

How to know how much money I have left on my Itunes card?

My friend gave me a 25dollar gift card to I-tunes and so far I spent 1.29 on one song. On other answers people said that you would see your balance on the top right corner of the Itunes and I'm just really confused because those answers were given 2 or more years ago and I'm postive the ipod had some update that changed that. So question is: Where can I check how much money I have left on my card? And once I put in the code and buy songs, those songs are immediately free right? PS Don't say I'm lacking common sense. I'm just really cautious about these types of things. :3
