Any websites that sells iPhone 5s for cheap?

Anybody knows any websites that sells iPhone 5s for cheap?

Why don't you just get a four, they are cheaper!

If you live in canada, there's a site calle kijiji.ca where people will sell their used items and sometimes they would even be brand new. I looked on there to get my 5S and I found like ten people who were sell theirs in good condition for like $100.
Also, some phone companies have the option of getting a pre certified phone rather than an new phone. These phones were used but returned but were fixed up and everything before the company would resell them. I got my 5S for like $60 at koodo. The previous owner only had it for 14 days. It was practically brand new.
