Apple’s retail stores have started to match retailers’ and carriers’ discounted iPhone prices, according to a new report. Citing an unnamed source, MacRumors reports that the stores have received authorization to match “Market Support-approved” prices from major retailers and carriers. As such, a discount of $49.01 will be taken off select iPhone 4 and iPhone 4S models, depending on the carrier. The report notes that customers will likely need to cite the source of the lower pricing in order for Apple to honor the offer; the policy appears to apply only at Apple’s retail stores and not to online orders.
