Buying iphone at 17?

No.

As long as you can provide a payment method for it online it can be bought regardless of your age and you can pick it up at a store also regardless of age.

If you are trying to reserve one online and then pay for it in store, then that you cannot do, regardless of age.

Payment needs be completed online.

Yea thats what it says on my post that i want to pay in full on the website

You can do that just fine if you have a payment method that can cover the payment. Your age won't even be requested or judged in any way.
