The company, usually reluctant to alter pricing, will take up to 600 yuan ($89) off the price of its top-line iPhone 13 Pro series between July 29 and Aug. 1, according to a notice on its website. To be eligible, buyers have to use one of a select number of payment platforms, such as Ant Group Co.’s Alipay. Certain AirPods and Apple Watch models are also part of the promotion.
