Is amazon trustable for buying an iPhone?

It's around 600 that's a lot i need to know of I can trust it!

I've used amazon many many times. Amazon isn't who you should be thinking about trusting, its the person youd be buying from. Think of amazon like ebay, its a site where you can put things up for sale. However amazon will make sure they do the best they can to help you get what you asked for, they have very good return policies aswell. However, no matter what, i think its all around safer to visit a best buy, walmart, or even order it from apple.com or try to find a store. Hope this helped.
