Who can sell iphone cheaply?

I want iphone the cheapest.mint iphone may be a choice

Best way it's to go with the contract

EBay or Craigslist. If you want it brand new lean towards eBay. I have been selling and buying things off eBay for years. I would go look it up on eBay.

Older versions of iphone are quite cheap but you won't want to buy them because… Hey they're outdated.
I would recommend you to go to www.ankaka.com and buy your self a cheap and reliable iphone from there. You can get it delivered at your doorstep anywhere in the world.

It is the cheapest if you go with a phone store like Verizon, at&t, or sprint. If you get a 2 year contract with them it will be even cheaper.
hope this helped!
