A lot of my friends like the 'Chase Sapphire Preferred Card', but I do not like to pay an annual fee.
It seems like the typical rewards cards give you 1.5% back on what you spend.
Since I always payoff my balance, the interest rate is not a factor when I choose.
I am considering 'Citi Double Cash Card' as it pays 2%. 1% when you buy, and 1% when you pay your bill.
