Unfortunately for some of us, buying fresh for each batch involves either ordering more than a week in advance of planned brew day, or a 250 mile round trip to the LHBS. Under those circumstances, I prefer to do the Boy Scout thing and "be prepared". One of the reasons I bought a larger house than I really needed 30 years ago, was so that I didn't have to pay other folks a premium to warehouse stuff for me. In BFE, JIT is a laughable concept.
