Hi, Someone asked me to report when oca became available in bulk locally. (Berkeley CA) It is now at Berkeley Bowl (The Shattuck Ave Store) it is selling at about $6 a pound. There are red and pale yellow tubers. The tubers range from 2 to close to 4 inches long, and roughly 1/2+ inch thick. If there's a substantial interest, I could buy some and ship them off to Dell; one or two requests, I could deal with privately if that is ok. Liz W
