If I'm going to spending money, I may as well be making a little bit back in rewards points. What are some of your favorite rewards credit cards? Mine include:Amazon Rewards Card - 3 points for Amazon purchases (I buy everything on Amazon), 2 points for major categories like gas, drugstores, restaurants, etc., and 1 point for everything else.Chase Freedom Card - 5% cashback in revolving categories every 3 months.Continental Rewards Card - 25,000 - 50,000 miles are awarded just to sign up. That in itself makes this card worth it. Not to mention you can have 1 free checked back for up to 9 passengers booked using the credit card. Unforunately, there is an annual fee, but it can be worth it. If not, pay 1 year's worth just for the initial miles to book yourself a trip and then cancel (If you don't mind the slight credit hit). I'll generally use my Amazon Rewards credit card for most purchases and then switch to Chase Freedom for categories receiving 5% cash back. I use Continental for any travel expenses.
