The site displays exactly which Apple stores all over the world have AirPods available for purchase -- right on a simple map, per the report. Of course, Apple's official website provides the same information when you search for availability with your city or zip code, but this way, you can see all of that information visualized and at a much larger scale. This could be particularly helpful if you know someone who lives near an Apple store in another city and wouldn't mind stopping by to grab you a set, especially if you'll see them over the holidays. The site also shows inventory information for iPhones, MacBooks, and Apple Watches.
Of course, if you find a store on the map with AirPods in stock, you should definitely verify their availability via the traditional method on Apple's website before walking into the busy store and demanding them. The tool makes this step easy with a "Check at Apple" button that takes you to the company's online store, where you can go ahead and purchase them for in-store pickup -- you know, to avoid crushing disappointment.
