Apple retailers frequently discount iPhones, Macs and iPads for Black Friday.
Apple Launches U.S. iPhone Promotion Offering Free Next Day Shipping On All Models
The shipping promotion comes shortly after Apple released a new "Why You'll Love an iPhone" advertising campaign via email and the web and a secondary email advertisement that highlighted Apple’s 9th consecutive J.D. Power Smartphone Satisfaction Rankings win. Apple's advertising push follows the introduction of Samsung's Galaxy S 4 phone.
Potential customers are limited to purchasing two iPhones with the newly released shipping offer, which is available immediately. Though no specific holiday is associated with the promotion, it does come a week before the Easter holiday.
