The Apple Store is currently down in anticipation of the iPhone 18 Pro pre-orders, which begin on Saturday, September 12, at 5:00 a.m. Pacific Time, with a launch scheduled for Friday, September 18. To secure a launch-day delivery, quick ordering is essential as shipping estimates can slip within hours for popular configurations. Customers should utilize the "Get Ready" feature in the Apple Store app or online store to pre-select their model, accessories, and payment methods for a faster checkout. It is crucial to verify Apple Account details, including payment information and shipping address, beforehand. Completing trade-in quotes in advance streamlines the process by avoiding additional steps at checkout. Former iPhone Upgrade Program members should check their status and replacement financing options. Ahead of time, ensure the Apple Store app is updated and open with the saved configuration, and also keep Apple's online store open on another device, as either may become accessible first. Avoid making last-minute configuration changes during checkout to prevent inventory re-queries and potential availability issues. Opting for in-store pickup is a viable alternative if offered, as its inventory is often separate from delivery stock. Lastly, launch day walk-in stock remains a genuine, albeit uncertain, alternative, with Apple's pickup availability checker updating throughout the morning.
