I guess to me $5.95 for what is, after all, a pound of corn isn't what I'd call "cheap". Canned hominy is readily available here in grocery stores but I've never been satisfied with the quality when it's used in posole, too beat up. And don't ask me about the time I tried freezing the stuff
The giant cans were on sale, cheaper than a small ones, so I used some and tried freezing the rest. I figured I'd still be ahead even if it didn't work . And it didn't: total mush.
So I've been looking for dried, with no success until recently, when I found Los Chileros brand in a couple of Seattle-area stores. I thought it pricey at $4+ for 12 ounces but that's no worse than what you're looking at with Rancho Gordo. Haven't tried it yet, so can't vouch for the quality, but it looks good. This
might be another option for you: Amazon shipping isn't that bad and free if you can scare up $25 worth of stuff you want. A half dozen bags of posole would put you most of the way there!
