Apple has a little known “Reserve and Pick Up” website where you can check if a certain Apple product is in stock at a certain Apple Store. Apple has just added the Apple TV to this web portal and it’s now the perfect way to check if your local store has any of them in stock.
Unfortunately this site is U.S. only and you can click here to check your local store.
Note: This post is not showing you can reserve an Apple TV, this post is showing you that you can check if the Apple TV is available at you local store. Also, it’s a good idea to call your store first and not trust Apple’s website. BTW: Does not work in Google Chrome.
