Several times in recent days, we've mentioned a website called Apple-Tracker.com that was allowing customers to easily monitor in-store Personal Pickup availability of iPhone 5s and iPad Air models. The site offered a much more efficient method of checking for availability than on Apple's online store, showing product availability of all capacities of a given color/connectivity combination at the 20 closest retail store locations to a given zip code on a single screen. In contrast, Apple's online store requires users to select a single color/connectivity/capacity combination, enter a zip code, and then navigate through four pages of availability listings to see all 20 closest stores.
