Hey Lorinne -
I think the messaging here isn't as clear as it could be. All chromas won't be available for BE. In the past, only chromas that are 6+ months ore more old would go on sale, and I believe that's the case here as well. I'm catching up with our store team now regarding the messaging in the client 'cause I can see where the confusion may lie.
Basically, the messaging is meant to imply 'hey, any chromas that are selected to be available for BE will be located here', as opposed to 'hey, all chromas are available for BE and you can find them here.'
Sorry for the confusion. ;-;
