Apple Retail Stores Begin Price Matching iPhone Discounts from Carriers and Major Retailers
But a source has now revealed to MacRumors that Apple's retail stores have been given authorization to match these discounted prices from approved major retailers and carriers. In all cases, Apple will discount iPhone 4S and iPhone 4 models by $49.01 upon request to bring pricing down to $349.99/$249.99/$149.99 for the iPhone 4S and $49.99 for the iPhone 4. As with most price matching offers, consumers will likely need to cite the source offering the lower pricing in order for Apple to honor the price match.
Notably, the price matching policy applies only to Apple's retail stores and is not available for orders through the online store.
