Zimbabwe's $100 trillion note(s)

Zimbabwe's hyperinflation has become so extreme that the treasury is rolling out 10, 20, 50 and 100 trillion dollar notes. 100 Zimbabwean dollars are currently worth US$30. Now, quick! Go spend it before it's too late. That is, if there's anything to purchase with them...
However, the dollarisation of the economy means that few products are available in the local currency [...] Some shops are licensed to sells goods in foreign currency but everyone from vegetable sellers to mobile phone service providers peg their prices to the US dollar.

Most groceries are brought in by Zimbabweans from neighbouring South Africa, Botswana or Zambia, further driving up prices. There is more than 80% unemployment in the country and those with jobs find their salary is worthless unless they are paid in foreign currency
