Anyone know of an inexpensive way to get Marmite from England?

My girlfriend and I just moved out here a couple of weeks ago and are here permanently with my parents who have been here for about 5 years. My girlfriend is British and that's about all she really misses (besides good ingredients for Yorkshire pudding and other English dishes). I'm American and have adapted well out here already.
