Fifty Dollars

If you had $1000 sitting in your checking account, you wouldn't really pay that much attention to how you spent $50 of it as long as your basic needs were met. Even if that meant that 90% of it went to bills and living expenses.

However, if someone gives you $50 gift certificate, it seems that one becomes savvy and shrewd in an effort to extend that $50 as far as it can go and only on the most worthy of things.
