Another way to make a quick buck, is to buy bottled water and sell it at a marked up value at a tailgate or event.

Another trick when using cash back credit cards is to use a particular credit card that pays a higher cash back percent on certain purchases in any given month. For example, the Discover Card recently offered 5% cash back on gasoline purchases from January through March of this year, whereas some other cards were only offering 1% or 2%.

Another cash back card is American Express' Blue Cash Everyday. For groceries you can earn 3% cash back, for gas 2% and for everything else 1%. There are no annual fees.

I am a fan of the discover card, discover.com. During certain months, I get 5% cash back on certain purchases and 1% on all other purchases. For example from January through March of this year, I received 5% cash back for purchases made at gas stations. For on-line purchases, you can received a higher percentage of cash back for certain purchases.

Earn Money Using Your Credit Card

If you qualify you can get money back for purchases depending on the terms of the card. For example, put $10,000 on your 1% cash back credit card and get $100 back. This is an excellent website to compare credit cards, although there are dozens of other cards and competitors other than what is listed out there:
