Think reward points never add up? Just open the Citi Diamond Preferred credit card and get 6,000 points. Next, refer your friends and family (limit of 5) and get up to 25,000 additional points. That's 31,000 points without spending much money and you're well on your way to get some cool stuff (free)!

Next time you want to purchase something online that requires a credit card but don't want to sign up for the recurring subscription charges; request a temporary credit card number from your bank. Now-a-days most big banks (ex: Citibank) offer disposable credit card numbers for one time purchases. Sign-up and within minutes you will be provided with a temporary card number that will allow you to purchase your item(s) without having to worry about canceling subscriptions. When the merchant tries to re-bill your credit card, their charge will be denied because the card is no longer valid. Pay for what you want, not what they want!
