Not sure about their shipping, if I recall it's not too bad if you order a decent quantity. I ordered about 90# of various specialty grains, came out to about $0.98/lb for shipping cost, or around $89 total. Not bad.
I don't mean to come off like I'm trying to promote their product, it's just reaaaaaaalllllllly friggin' exciting to me that I can just *buy* any kind of specialty grain now. Assuming their grains are high-quality, that means I can literally make any kind of beer I want now, with proper color and (presumably) proper flavor. I haven't used their crystal yet so I can't necessarily endorse it, but in the coming months I'll definitely have something to report. I ordered 25# each of crystal 20 and crystal 60, as well as 25# of black patent millet malt and 5# of black unmalted buckwheat rated at 400 SRM (plus some pale millet malt to compare to Grouse). I have no idea why this entire board isn't creaming its collective shorts over this, because to me, this is pretty much the start of the revolution!
