Vegemite - love it or hate it, if you're an Aussie you'll have an opinion on it! Other countries, less so, as the Australian Foreign Minister found out once when US customs couldn't believe you'd eat it for breakfast...
As an Aussie living in the UK, if you are of the "love it" persuasion, and you haven't managed to bring (enough) of it home from your last trip, where can you buy vegemite?
