You'd go to the black market.

This is what happened in Soviet Russia (I'm not joking. See source):

-You'd work in a plant making toasters. Every now and then, you steal a toaster.

-The bosses turn a blind eye because they also steal.

-You exchange your toaster for an iron with a worker from another factory.

-He exchanges your toaster for a thick jacket and boots with someone else.

-etc...

Of course, you could always not steal a toaster and requisition for an iron, but then you'd have to wait 10 years.
