I need an iPhone where can I get a cheap one?

I need an iPhone because I want to surprise my cousin but the problem is my parents can't find any help where I can get a cheap one

Well, second hand iphones are still available and they are of just around 200$max.

I have found many of the best discounts on Amazon. But you have to use the correct discount link.
This has always been the best place for Amazon discounts. Save this link under favorites and keep using it. I use it all the time and I find lots of bargains.

Best buy they sell iphone 5 for 45 dollars but it comes with ios 6.1.4

Craigslist or ebay. If you use craigslist make sure you go with someone like your parents or a friend and meet the seller at a public place(like starbucks). Also test the phone before buying it. Use ebay if your parents let you.
