Following Trevor's lead, I called HopUnion this morning to see what they had available. Out of the dozens of varieties that they usually stock, they had but one: Argentina Cascade. They're described as similar to Spalt, which I love, so I ordered two 44-pound boxes at $19.50 per pound. It's a lot of money, but it should just about cover my needs for the rest of the year, so I won't have to worry about hops any more.
I also ordered enough Briess malt to brew ten batches or so. Some of those prices have gone up as much as a dime a pound since last time I ordered malt.
