Apple has updated its third-party USB adapter trade-in program page to note that the program is worldwide. Apple originally only noted support for the program in China and the United States.
The company then updated the page to share that customers in Australia ($14 AUD), Canada ($11 CAD), France (10 €), Germany (10 €), Japan (￥1,000), and the United Kingdom (10 €) are eligible as well.
Now that the program has officially begun, Apple has providing special discount pricing for official Apple USB charging adapters for several more countries (shown above). Not all of the countries have official Apple Retail Stores, but the program will take place at select authorized resellers as well.
