Do you have a Gordon Foodservice (GFS Marketplace)? I was able to find bread flour there. It's bleached which I usually avoid but will compromise on for now. Funny story, I ordered it through Instacart with a bunch of stuff for my mom and had it delivered to moms house. It was a 25# bag. Sent DH over to pick it up from mom's front porch. He comes back "You ordered 50# of flour?!" Turns out 2-25# bags were shrink wrapped together and neither the Instacart shopper nor the cashier noticed. I'm up to my ears in bread flour.
I found gluten on
Amazon sporadically. Found Bob's Red Mill wheat gluten at Jewel (Albertsons) last week after trying to order elsewhere using Instacart. The poor Instacart shopper was so confused. She kept sending me pictures of everything gluten free in the baking aisle.
