Well, here in the East Bay of the Bay Area, I can get it at three places:

• Whole Foods (Thai Kitchen, $1.59/14 oz.can) (True Nature, $1.39/14 oz. can)
• Safeway (forget the brand-- some Thai name, 1.09/13.5 oz. can)
• Country Square Market (forget the brand-- some Thai name, gf bought it)

The one at Safeway is too sweet (though sugar isn't listed in the ingredients, I suspect it's there) for my tastes. The CSM brand is actually salty--bleah!. So, it's the Thai Kitchen for most things, and the Safeway brand for curries for now.

I will try the True Nature Brand in the next week. I'll post my experience in this thread.
