I just picked up a second one at my local Best Buy. I noticed on the website it said "in store only" so I called and long story short they had two. They were not on the shelf, but instead in the "return bin". My guess is that someone bought them, kept the Netflix code, and then returned them. Both were unopened and never used. When I purchased, it did give me another Netflix code as well, so that is still active in Best Buy stores unless these are from the first batch and there is a special UPC code for that. I tried to use it again on my account, and it was going to let me, but it says for me to wait until my current three free months expire before entering the code again, so that's what I'm going to do now.
Anyway, if you notice on the site it says "in store only" and you go in and you don't see it on the shelf where it should be and they can't find them, just ask them to please check the return bin.
Just a heads up!
I've already got the second one up and running in the bedroom now. Awesome!
