Marmite

I was reading today that there is currently a shortage of Marmite.  It's a by-product of the brewing industry so once the pubs all closed beer consumption went down, less beer was brewed and Hey Presto!  No Marmite.  A foreseeable consequence?  Possibly.  But while everyone was out buying loo rolls look what I got.  I'm open to bids; should we start at, say, £100?
