if you're tolerant to wheatsies sharing the same belt Sami's makes a flax and millet bread that's seriously super good. we keep it in the fridge and it's yummier toasted, but it's really great (the bagels are gf&v too): http://samisbakery.com/our-products/millet-flax/
(we order a bunch online).
Kiddo, i'm a bit obsessive when it comes to the pantry, but i used to have a chart that kinda took stock of what i had in the house and what i needed. it was pretty darn helpful. these days i order a lot of the gluten-free flours on amazon and they're usually a box of 2-4 bags of gluten-free flours so i usually have a bunch on hand. i totally hear ya on your frustrations though - i'm sorry!
We also love this bread! I haven't yet bought it in bulk because I put a few loaves in my online cart, and then the shipping cost comes up and sucker punches me in the gut :/ I don't know why Whole Foods won't carry them! They don't sell one single vegan and gluten free bread item in several of their stores in Massachusetts. What the heck?? I can't be the only one to ask them to?
