Is it cheaper to buy an Iphone 5 from Apple or Verizon?

I'm looking to buy an iphone 5 and i was wondering which would be the cheaper way? I'm under a 2 year contract with Verizon and my upgrade date isn't until August. I'm not the account holder but my name is on the account. If i go with Verizon i would have to pay like 650 plus ill have to pay 9.99 a month for it. If i go to apple.com the phone starts at 199 but they are asking my if I'm buying for my Verizon account. Of course i'm but they are asking me for my number, billing zip code, social (of the account holder) and the billing password (which i know). I filled it out and i keep getting a message saying incorrect billing password. I've tried several times and same thing. So I'm wondering has anyone bought an iphone from the apple online store, if so is it cheaper? Do they add additional charges? Or should i just buy it from Verizon? Help! I want an expert answer and Explain why. Please and Thank you!

The $650 price with Verizon is because you're seeing this price after they've already identified your account, so they know aren't due for an upgrade yet, so they are going to make you pay full price.

The $199 price from Apple is the discounted "new contract" or upgrade price that anyone can get if they want to start a new contract (because iPhones cost a lot more than that if you get them without a contract).So I'll bet that once Apple identifies your account, you won't be able to get the phone for $199 (unless you want ANOTHER contract!).

I'm 99% sure that once Apple has your account details, the price will be the same as Verizon's ($650).
