What Can You Buy with $5.00

Ever been with only $5.00 left in your pocket til payday?  I have and it's not fun.  I mean, can you buy anything for $5.00?  How much will $5.00 buy around the world?  Can that same $5.00 buy you more in the US or down under?  These are the questions that keep me up at night and I found some answers.
