Guilty on both counts :) Although you have to search a bit for it here in North America. Marmite is more easily available since it has a shorter trip to make.
When I go to England I bring back a big jar whatever the metric is for 2 pounds (1,000 grams ???) of Marmite for just 2 pounds sterling...about $2.50
here it costs $6 for about 6oz...if you can find it...Publix have it sometimes...
Hot white bread toast, butter and Marmite and a cuppa Tea with milk and sugar...
