Found this today:

http://www.costcoconnection.com/connection/ks_wine/

The site has a page for each of the Kirkland wines, and goes into
depth on each.

Btw, I'm pretty sure the Nalys CdP is gone, and I don't recall seeing
the Napa cab on the shelf. I sure wish we could get the 18-year-old
Scotch here in Seattle, but we have a 19th Century liquor control
system.

Btw, we opened another bottle of the Nalys last night, and it was
excellent, if a bit young. Pretty thick, probably due to the high
amount of syrah in the mix (40%). I also had a report on the Kirkland
Alexander Valley cab. From a thoroughly unscientific but
oenophillically appreciative source, an enthusiastic, "Not bad!!!"

P.S. Made a great discovery regarding Costco in South San Francisco.
It's on the corner of Bel-Aire Ave and North Cargo Road, on the way to
SFO's Rental Car Return. Which means you can gas up (if you're a
member) at the cheapest pumps around, and if you have room to pack a
bottle or two in your luggage you can dash in and score in the liquor
dept. Maybe even grab a bottle of 2005 Mick Fleetwood Cab for $20.
