You'd buy bulk Crystal 10L?
I have a dozen 6.5 gallon buckets with GammaSeal lids storing grains, but it's mostly 2-row, Maris Otter, Bohemian Pilsener (2 buckets each), and the rest are "specialty" malts I use often (Carafoam, Caraamber, Vienna, etc.), and even those, I only bought half-sacks.
I simply don't have enough space to buy EVERY possible malt I could ever need in bulk. Does anyone? Do you really buy 25kg sacks of Crystal 10L through 120L, plus roasted malt, chocolate malt, Munich, Caramunich, Thomas Fawcett Amber, and everything else? There are some malts it just doesn't make economic sense to buy in bulk, and for those, I (for a brief period, anyway) relied on my LHBS. After getting burned, I learned my lesson and order such malts online now, a couple pounds at a time, as needed for upcoming recipes I'm brewing.
