Several retailers offer the iPhone at a discount, but most of these offers are not available exclusively online. Customers may also obtain these offers by visiting a retail outlet or by calling the retailer selling the iPhone. As of 2015, AT&T is offering the iPhone 6 for $0 down.
Though AT&T offers the phone for $0 down, there is a monthly cost of $21.67 per month for 30 months for purchasing the iPhone. AT&T also offers the iPhone 6 Plus at $0 down and a monthly price of $25 a month. Verizon, Sprint and T-Mobile also offer similar deals of this nature respectively.
