Apple is launching an Earth Day promotion enabling customers to trade in old accessories for discounts up to 10% on new purchases. Users can participate by bringing eligible items like AirPods, Apple Pencil, and Apple Watch bands to their nearest Apple store. However, items like data cables and power bricks are excluded from the trade-in program. While users can earn discounts, the maximum allowable discount is capped at $20. This initiative supports Apple's recycling campaign and enhances its existing trade-in program for various devices, including Android models.
