How much does the iphone 6 plus cost?

Google is telling me a bunch of different answers
i got bestbuy telling me it's $200
then some other websites saying $750

Added (1). edit: what's the difference between a contract and no contract

With the lower prices you are signing up for an account with a service provider so you are paying for the phone in the monthly payments over one or two years. You need to evaluate the various schemes to see which suits your budget and how you would use the phone. For $750 you are buying the phone but you will need to add your own mobile account to use it.

Depends on a few things but the problem you seem to be running into with the HUGE price gap is that you can buy phones outright to use on any provider you choose but you can also get a phone as part of plan with a provider, so the initial price is subsidised

Both are right… The lower number is when you get a 2 year contract with the phone… The larger number is the phone with no contract

Under a two year contract, a person used to get them for $200. But now, carriers are doing away with contracts, so the phone will cost the full price: About $750 or even higher, depending upon the memory storage and the length of the payment period. A major rip off.
