Good question. My closest Apple Store is also hours away.
Can you confirm that best buy stores are selling them now? I think it is inaccurate to say they are.
Yesterday best buy told me they'd have them Thursday or Friday. Today they flat out sad they are NOT selling theirs until Friday. I can't preorder because I want to trade in my iPad 3. (I'm actually writing this in the Notes App because whenever I try to type a post on a forum, Safari freezes after a paragraph or so and I lose everything I typed. Hence my eagerness to upgrade (iOS 8 and iPad 3 don't mix).
Whenever I call any Walmart in my area they don't even know what I'm talking about. One manager told me "I haven't gotten an email about this yet," whatever that means.
Target has a history of ignoring release dates altogether and selling things as soon as they get them. I got a Harry Potter book, Skyrim, and the iPad 2 days before anyone else. But you have to drive there to see and their trade in program is about 40 percent stingier than Walmart and Best Buy.
Hope things change tomorrow.
I'm very anxious to hear from someone who actually purchased one at any of these stores.
