Where can I find fine milled blueberry flaxseed? Thank you!

I've never heard of "blueberry flaxseed." As far as I know, blueberries and flax seeds come from two very different plants unless there's some new strange gmo I don't know about. However, for fine ground flaxseed, simply buy whole flax seeds at any health food store (buying already ground flax meal is not a good idea in my book--it goes rancid quickly), and grind them in a spice grinder. Hope this helps.
