Is it safe and trusted to buy iphone 5 or 5s from amazon?

As you can see my question. Well, i'm really wanted to buy iphone 5 32gb not 5s cuz i don't have enough money.So, i found some iphones 5 from amazon and most of them are cheap. Also, i wanted it factory unlocked but i'm worry if i ordered one, it might be locked. That what it worries me due to the comments from other people about it.So, i'm afraid and i don't know is it better to buy it from amazon or not?

Please any help and thank you ^_^

Generally speaking yes, if you have doubts try to contact the seller.

For me, I never had a problem with Amazon. I'm sure you're safe to go with it.
