Dear Marmite lovers,
Marmite might be disappearing off our shelves for a little while. But don't fear. It's essentially a brand for a particular product. While others may say Vegemite (and let's face it, the difference there is less than the difference between Pepsi and Coke), but there's also Promite, Cenovis and AussieMite.
In fact, even Marmite might make a suitable replacement. It's also produced in the U.K. and South Africa.
So for those of you spending stupid amounts of money on TradeMe - stop trying to defend a brand. While it's unfortunate Sanitarium can no longer produce Marmite (at the moment), it's really not as unique as they'd have you believe.
The sane people of this world.
