Where can i get a unlocked refurbished iphone 5s cheaper than 500 dollars?

I have wanted an iPhone 5s ever since it came out, and my parents can't afford to pay $700 dollars for one. My mom told me she would try and get me a refurbished unlocked one (we're on straight talk, we can't afford a contract service) for my 8th grade graduation, which is in one year. Does anyone know where I can get an unlocked, refurbished iPhone 5s cheaper than $500?

How to use a foreign iphone in the US?

So I had a relative return from Okinawa, Japan, and she brought home her iPhone 4s that she used overseas with the carrier JP AU I think. She gave it to me and said I could have it. She factory reset it and everything. When I went to start it, it asked for a sim card. I put mine in and it said that the phone couldn't be activated or something like that. I went and bought a sim card to try and jailbreak it but I can even get the phone to activate to even do that. It won't go past the start up screen because it says it can't be activated. I think it has to be some sort of restriction that stupid company put on the phone. Is there some way to remove that restriction so I can use this phone?

Just got an IPhone 5S! What is the best case I can get for it?

So I finally got an iPhone 5S and have never owned an iPhone before. I'm most likely going to order it from amazon or eBay just because I don't want to pay retail prize. What's the best case for this phone? Can you please provide me with the name? Or even better, with the link to one of these? Not really a prize range. Just want the best. I have insurance, but wouldn't like to break it.

How to get my grades up in 2 weeks?

So my other grades are A's but I have History and Science that are So close to being A's (for the semester). My history grade is 87 but the semester grade is 89 and my science grade is 87 but the semester grade is 88. I need my regular history grade to be at least 90 to make my semester grade to be an A. I need my science grade to be at least 91 or 92 to make my semester grade to be an A. This might seem confusing but it also takes in my nine weeks' grade from earlier. Yeah, thats probably confusing too.
But anyways the school year is almost over and my mom and I agreed that if I had all A's for the semester, I'd get an iPhone, something I've been wanting for So LONG. I'm so close and I can't give up but the school year ends next Friday.
Something you should know-- I'm pretty sure my science teacher isn't going to give extra credit assignments because he told me that a couple of weeks ago. I'm also not sure if we're having finals in science but i know we're in history.
Please help me! What can I do to get my grades to be all A's?!
