I have money on my iTunes but don't need it?

Ok so I was so desperate to buy the Nicki Minaj official app or whatever. So she say her Nicktionary terms… Ok anyways I bought a $15 dollar iTunes card because that was the lowest price one I really wasn't thinking but I don't want anything else from the app store or iTunes movies and shows are too much and I don't want anything. Can I trade somehow the money for something or get the 14 dollars back I know its not a lot but its too much to just be laying in my apple account.
P.s I have to many pictures and songs so I have no storage left to buy anything even if I wanted to i'm getting a Iphone soon hopefully with answers to my last question so Can someone help? Or naww

Can I buy an iPhone 5c as an Ipod?

I really want the 5c but I don't want a contract or anything but i'm not going to pay $500 dollars for a phone i'm not using as a phone. The reason why is because I have a phone to make calls and that's pretty much all your paying for and for service. But I want to just use it on Wi-Fi. I want a green one and I can go to the app store and just download apps for calling. Anyways I really need help on this. I have about $120 dollars and i'm trying to get it before I move.

Iphone 4 cases that ship to Ireland?

I have an iphone 4s and i'm not able to find a cute case that protects my phone (comes around at the front sides so it protects my screen when it is put down screen facing down) that ships to ireland.

i tried amazon and i found a few that were really nice but don't ship to where i live. If anyone knows of any website i can look on or give me a link to a nice case i would really appreciate it.

One bluetooth receiver and multiple transmitters?

I need a bluetooth receiver to receive a signal from few transmitters. There's extremely little information about bluetooth hardware on the internet. Google gives a lot of topics about android and iphones, but that is not what I'm looking for.

What if we will take something similar to this one: http://www.mdfly.com/index.php?main_page=product_info&cPath=8_52&products_id=1047 Is it even possible in theory?

The real problem is that receiver should be smaller than transmitters. So it is impossible to put few receivers in one box.

If you will prompt me which way to dig, I will be truly grateful for you.

Here is a small pic of what i really looking for.
