That's 6/9 colors you can't walk into a store and buy today one month past launch. I'd call that an abnormal shortage based on past precedent. It's been this way for at least a couple weeks too with no signs of improving, shipping dates continue to push out by another day every day.
Red, white, and stone are the only colors you can buy in store today here. Something is wrong with the supply when you can't even buy basic black in store which is a bread and butter, steadfast, non-exciting color that people don't go out and buy in droves all of a sudden like they do with Spicy Orange/Flash/etc.
They generally aren't out of stock in store of 70% of their cases, especially a few weeeks after launch. When else have they been out of 70% of their choices in store? Never that I can remember.
