The only person who can best assess how to prepare is YOU.

Take a look at your expenditures...cash/credit/check.

What can you live with, what can you not live without?

If you have no fuel for your vehicle, can you walk to where you need to go?

If not, is a bike available?

What is the climate where you live. How do you stay warm/cool?

Look...it's simple. Divide your purchases into ESSENTIAL and NON ESSENTIAL. For every ESSENTIAL ITEM, what is your backup plan...or PLAN B?

If you don't have a PLAN B for ESSENTIAL ITEMS, GET ONE NOW!

By the way, beer is not ESSENTIAL no matter what you think
