I wandered into Montclair Produce (2220 Mountain Blvd., Oakland, in the small shopping center up what looks like a driveway next to the 76 Station at the head of Park Blvd.)
They are selling cryovac Snake River Kobe beef tri-tips for the introductory price of $8.99/lb. At that price, even if it's not as good as "real" Kobe beef it's a good deal. Don't know how long the "introductory price" will last -- they said they'd been selling it for a couple of weeks. The tri-tip was the only Kobe beef they had.
If you have any suggestions on how I should cook the 2.5 lb. piece I bought, I started a thread on the general topics board.
