Past Spending

• One of the hallmarks of cash back and rebate cards is their tiered earnings structure. Many cards now pay a set percentage for certain categories of spending, including gasoline purchases, restaurant meals and purchases at retail stores. One way to get the biggest bang for your buck is to review your past spending. Order a year-end summary from your current credit card company, or review your statements to check your spending levels in each category. Then choose the card that gives you the greatest reward percentage in the areas where you spend the most.
  
  

Use the Right Card

• If you carry more than one reward card, choose the cards you use carefully to maximize your earnings. For instance, if one of your cards gives you a 5 or 10 percent rebate on gasoline purchases, use only that card when you fill up your car. Choose the card that gives you the biggest rebate for dining out each time you visit your favorite restaurant, and use the card that gives you the most airline miles every time you fly.
  
  

Annual Fee

• Some reward cards charge an annual fee, while others do not. Depending on the rewards you receive, it might be worthwhile to pay the annual fee, especially if you earn reward points for every dollar of that fee. If you prefer not to pay an annual fee, there are plenty of free credit cards on the market.
  
  

Bonus Offers

• With credit card companies fiercely competing for every available customer, you might be able to get a significant bonus just for signing up for a new card. Look for bonus offers in your mail and online. Credit card companies routinely offer perks like credit statements, free gift cards and even free airline tickets for those who sign up for their cards. You might, for instance, be able to earn enough bonus miles to get a free round-trip ticket, or enough bonus points for a $100 gift card or even a check.
