What's the cheapest you can get an iPhone 4s?

For my birthday this August I'm asking for an iPhone 4s, my family doesn't have the most money in the world; so it would be the only present I get. Anyway, at the moment I have an iPod touch 4th generation, so I was thinking of selling that near my birthday to help my parents get the money.

I was looking on Amazon, and found an iPhone 4s for £295, is there any other places apart from eBay and Amazon where I could get a cheap white iPhone 4s?

Thank you so much! [:

P.S I don't want to get one on contract

If you want an iPhone not on a contract then they will be more pricey. I'd suggest looking through your local classifieds for used iPhones. Another thing to consider is which carrier you will use the iPhone on, which may determine whether you want to get a factory unlocked iPhone or not.

That'll be a hard one because, iphone 4 is now free thru contracts and iphone 4s is 99$ thru sprint i know for sure but pretty its the same with others. And thru sprint their only 80 bucks for just one phone plan & good luck my b-day is august 5th and mother's the 27th of august. Just saying mad random lol

Sorry this will not be the answer of your question but.
if you think their is some problem in affording that 4s, you should get some cheaper one.

I ll suggest you to not to sell your iPod and get an android phone like xperia sola /p,
these phones are much cheaper than 4s, also according to me xperia is better in style than iPhone
