Yup, I just discovered this for myself too, as I've been checking Best Buy's website daily for availability of the Apple Pencil, and also for the availability of the smart keyboard. I placed an order for the pencil through Best Buy's site, and I got an estimated expedited shipping arrival date of 12/15/15 for receiving it!!
...Much better than my prior order for the pencil through Apple's site (which I've since cancelled), where I had an eta of receiving the pencil sometime the first week of January '16.
A Christmas Miracle !!
It was for me...
As I placed my original order for it from Apple mid November, with an early January shipping time frame for getting it. Which I was okay with, since I didn't want to go the route of getting one off of eBay at double the retail price (at a minimum) for bidding/winning an 'in hand' auction for one. But... Since Best Buy's got them now, with a shipping/arrival time frame of next week for getting it, I figured why not, do I did, and I cancelled my other order.
Been checking daily quite early in the AM. Always shows unavailable. I know it's been said before but Apple has really let me down with the lack of stock on these. Perhaps they didn't think there would be such a high demand/interest but I would have hoped that by now the stock would be plentiful. I actually thought there would be a limited supply of Apple TV's when I went out to get one and those were available everywhere!
Shipments don't typically arrive early a.m. I have seen them for in store pick up typically in the afternoon.
