Some seasonal flaps will come with, since Chanel is doing so much LG on Seasonal pieces lately. I have a Black Chevron w/ LG. But other than that, you don't usually see Black done in a seasonal variation.
Anyway, since the classic Black are permanent Or "revolving" while your store may be out of stock at some points, they should always be being replenished. So I'd keep asking you SA or popping in the check if you can. Other than that, there is always the Stock thread in the Shopping section. You can check to see if someone posts their SA has it in stock. You can find the link to the shopping section at the top of the Chanel forum page with the other "pinned" threads.
