Can I buy an Apple iPhone 6 Plus from the Apple website without a contract?

I want to have an iPhone 6 Plus (even though it's huge I want the larger one for the apps, because I use a headset to talk anyway.) I need an iPhone for work and all I have is an iPod 4th gen. The 4th gen was good for about 2 weeks and then they came out with the 5th gen and it all went south from there…

Anyways. I want to buy it from Apple because it's cheaper than Straight Talks prices, by A LOT. (about $750 for a 16gb, but on apple it's about $499 for a 128gb.) So I wanted to buy it on apple but have Smart Talk. Is there some way I can do that? I want a 128gb anyway, because I work with kids so (under a GREAT amount of my supervision, and me holding my phone) I let the kids play games like Toca Boca brands as a reinforcer. So is it possible to do that or do I Really have to go with Sprint? Because $45 a month is way better than $80 for basically the same thing.

I accidentally dropped my iPhone 4s and now it won't turn on?

I can't try the "hit-the-home-and-turn-on-button" method cause my turn-on button doesn't work and i already tried charging it, but nothing

Added (1). the turn-on button is the button on the top. Also, i want a solution that doesn't involve going to a store.

Older Pioneer car audio system?

Will updating my iPhone software use more space?

I currently run on 7.0.4 and I could be running 8.4. I missed a few updates because I only use my phone for music. I have every megabyte devoted to music and I don't really see the point in downloading more software if it is going to take up valuable space on my phone. Would updating my software actually use more space, or would the new updates cause the software to become more compact? Some people tell me that the new software is significantly smaller but I seriously doubt it.
