GingerK -- there is both lupin flour and ground lupin. Just different textures of the same stuff. Is basically the same price for us if we buy from Amazon or direct through Carrington, so we buy two bags at a time for free postage from Carrington. I have been seeing it more often in stores but yes, is expensive. When husband was first transitioning to his keo diet, he missed bread type products more than he does now so did a lot more with the almond flour and such. At this point, we don't do much with any of the baking types of things, but still do quite a bit with the llupin We discussed buying some of the flour to try out with our most recent order and decided not to.
