We saw this deal earlier this month, but now the trade-in requirement has been waived!
Brad's Deals Editor Michael,
New and existing customers who get a 64GB iPhone 8 on an unlimited plan at Verizon can get a second 64GB iPhone 8 for free. This offer also applies to the iPhone 8 Plus and iPhone X and will take $699.99 off the price of the second phone if you choose to get another iPhone X or 8 Plus instead of the 64GB iPhone 8. The $699.99 device credit will be applied to your monthly bill after three billing cycles and will continue over the course of your 24-month plan. This offer is open to both new customers and existing customers who add a new line of service. Shipping is free and sales tax is charged in most states.
