Thanks all. Found it at Cost Plus. Haven't had a chance to see if
Trader Joes or the local supermarkets have it.

Interestingly, Cost Plus had 4 oz jars of Vegemite and 4 oz jars of
Marmite. The Vegemite was $2.99 and the Marmite was $5.99. I bought
the Veg first to see if I liked it, but I'm very curious if the Marmite
price difference is reflected in the taste.

Oh the taste... Extremely salty, full of yeasty goodness. Very
concentrated. A little dab'll do ya. Let's see what kinds of uses I
can find for it.
