CA,
Never seen it in the supermarkets, it's not that popular t othe masses..... But as YF says, try the local 'indian' shops. Note though that they often will stock only one brand so you may have to shop around. For example the ones areound here vary. Some have East end spices, come have Rajah, some have TRS etc...
Really suprised that it isn't on the web site. I bought a jar about 2 weeks ago....
