If you’ve received two separate emails from Apple for the same purchase, there’s usually no need for concern. This is normal.
Apple often sends two different emails for a single transaction:
• A proof of purchase
• A tax invoice
These are not duplicate charges. They are simply two types of documentation for the same payment.
If you believe you were charged more than once, or if the details on the invoices show different amounts or dates, we recommend contacting Apple Support directly, as Apple manages all billing and payments made through the App Store.
