The price all depends on your plan, but I was able to upgrade my phone to pay the tax on the phone (8.75% of 799.99) up front since I'm from California. Then, the price of the phone is $21.83 for 24 months which works out to 523.92.
They also throw in a JBL Moto Mod speaker which is worth 79.99. So you're basically getting a phone that is supposed to cost $720 with the 79.99 speaker mod for only $523.92.

You pay for the phone subsidy by paying outrageously expensive monthly bills. And the total, even factoring in the subsidy, ends up more expensive than just buying the phone outright and playing $35/month for MVNO service.
There are plenty of prepaid cell carriers that provide similar service at a fraction of the price. Just look for a deal on the phone that you want and BYOD to the MVNO of your choice. For example, if you need Verizon coverage, there is Total Wireless, PagePluse, etc. If you need AT&T coverage, there is Cricket, Straight Talk, H2O wireless, etc. If you need Sprint coverage, there is RingPlus, Virgin Mobile, Boost Mobile, Ting Mobile, etc. If you need Tmobile coverage, there are also plenty of options.
Now that postpaid carriers have their peak membership, they stopped giving out subsidy while still charging outrageous monthly fees. So there is really less incentive to stick with a postpaid carrier.
If you are new to prepaid/MVNO's and think your monthly bill is ridiculously expensive, check out https://www.reddit.com/r/nocontract as a starting point for your research.
