Apple stores only allow trade-ins for iPhone, iPad, and Apple Watch at present. If you're a MacBook owner, you can only trade in your old computer through the tech giant's website, although this could change in the future.
Beginning on June 15, Apple will reportedly allow customers to trade in their dated MacBooks at its retail stores in the U.S. and receive credits toward the purchase of newer models (via Bloomberg). The same trade-in program will allegedly kick off at the company's retail stores in Canada on June 18. In addition to acquiring credits for newer computer purchases, customers may also use the trade-in value for Apple gift cards. However, the new opportunity may not be available immediately to all customers as many Apple stores remain closed since March of this year due to coronavirus.
In addition, Apple is said to be planning to offer financing to customers who will purchase MacBooks, iPads, AirPods, or other devices through Apple Card. That means they can pay for those items via monthly installments with 0% interest.
