That's awesome! Our AMZ has been all over the place on delivery times recently, at least over this way. It's not uncommon lately to tack something onto an order and get it the next day, but I still have Duke and LC perpetually stuck back on "Order Received" after their having been estimated for the first of October just a week or two ago.
My Flash was stuck there too, but (coincidentally or not) I called them on that one this morning. In my typical Joe search, he showed (and still does) as available for delivery tomorrow (from Amazon, not a third party seller) for the low low price of $49

so I asked Alexa from their website why, if they had Flash in stock, mine still had no delivery date.
It replied that, while it understood that was a frustrating question

, it could not give me an answer and asked if I wanted to chat with a customer service rep. I declined, but left a thumbs down anyway for "answer was not helpful." Then, this afternoon I magically get an update that Flash (and only Flash so far) is now expected on Saturday.
I guess I would have to pay the premium to get him tomorrow... Still highly annoying, and smells like demand-based pricing. In case we hadn't pissed off the latest generation against capitalism enough already, WM and now AMZ are dabbling in capitalistic exploitation. And we wonder why these kids are warm to communism. /end rant
I'm sure it is all actually based on regional arrivals of product, but that doesn't make it any less frustrating when other stores already have product available, and even on the shelves locally in some cases, and AMZ is still apparently waiting for theirs to get to the east coast. I'd have cancelled the AMZ order and gone to WM by now had I not used AMZ gift card balance to buy them.
Oh well, you win some, you lose some - especially when trying not to go out of pocket more than necessary for my toys.
