With an eligible trade-in and activation on a Sprint Flex 18-month lease, Sprint offers the Apple iPhone XS 64GB 4G LTE Smartphone for Sprint for $0 per month for 18 months with free shipping. Excluding the trade-in value, that's $540 less than what you'd pay with T-Mobile ($30/mo.) and the best iPhone XS deal we've listed yet. (It costs $999.99 to buy without a contract.) Deal ends September 27.
