Bleached and Bromated Flour?

I’ve been using King Arthur 12.7 to make New Haven style apizza from home. (Vid of last nights pie attached)

The flour works great, but I’d really love to get my hands on some bleached and bromated flour without having to order huge quantities through a restaurant supply site. I’ve asked some local bakeries here in Southern California but to no avail.

Has anyone had any luck finding bleached/bromated flour through a B2C channel?
