Went to the Best Buy in Gaithersburg, MD last night and got my new Note 7.
Not a pre-order, have no interest in re-sale value, never got on a mailing list...
The process itself was a little complex as they apparently had to outright void my old purchase, then consider this a new purchase. It probably had something to do with it being outside of the 14 day return policy in their system. While it was a little more time than I had hoped for, the staff were very helpful and straightforward.
They did ask for all of the accessories and box, didn't feel like arguing as I had already bought a bunch of backup cables, etc. before all of this began, so I didn't really need them.
The service there might be slow, and I would say they are understaffed, but when you get them, they are helpful and knowledgeable, or at least will know who to ask if they don't know.
So if you are a stickler for all of the details, not sure what the experience is. If you just want to stop having a bomb in your pocket, and just want the phone you originally bought? It is fine.
