GSPfan,
I have pointed out before on this forum that in most of the U.S. you can order powder from various websites and have it shipped to your door. I do it a lot, partly because I can often find powders on the Internet that aren't in any of the several good-sized local stores here in Montana. Quite often, too, even with the hazmat fee required, plus shipping, the price of an 8-pounder is similar to many retail stores.
I just looked at a number of sites, and 760 was listed in stock at most.
