Tip #9: Free Gas

If you want to earn some free gasoline, there are multiple ways to do so. Going back to the secret shopping methods - there are several companies who shop gas stations. Find them. They often pay $10-$15 not for gas but to check out the dirty bathrooms and the stors. So, you do a little work and you get most of your tank of gas paid for. Then, get a rewards credit card from your gas station - i.e. Exxom, BP etc. They often offer 5% cash back or points for free gas. While you won't make a killing, wouldn't you like to break even and not pay for something in life!
