Believe it or not, Apple's iPhone 11 is free right now at Best Buy with installments

Apple is having no problem selling them “regular” iPhone 11 variants like hotcakes several months after the release of the newest iOS handset family, but that doesn’t necessarily mean certain carriers and retailers don’t need the occasional special offer to boost their own individual performance.
For one thing, you’ll obviously have to agree to pay for the handset’s price in monthly installments. But because we’re talking about a gratis phone… at the end of the day, that means you’ll be offered bill credits every 30 days covering the full retail value of a 64GB iPhone 11 configuration after two years. In other words, a grand total of 700 bucks will be returned to your account in the form of 24 monthly credits of $29.17 a pop.
Secondly and perhaps more importantly, you’ll need to be an entirely new Sprint subscriber or an existing one willing to open a new line of service with the nation’s fourth-largest mobile network operator to qualify for Best Buy’s bargain. But that’s pretty much it, which means there are no trade-ins involved or any other type of funny business. And no, the agreement you’re looking at signing is not a lease. It’s a good old fashioned device payment plan, at the end of which you will be owning your “free” iPhone 11.
But the aforementioned state-of-the-art A13 Bionic processor, speakers, software, facial recognition, and yes, even the dual cam system made the 6.1-inch iPhone 11 a decent deal right off the bat at $700, which means being able to pay nothing today by jumping just a couple of hoops is the textbook definition of a once-in-a-lifetime opportunity.
