Receiving 3% off of what you spent for your three highest bonus
categories sounds good. There is no limit to how much you can earn.
Many cards offer a reward rate that is comparable to the Chase
Freedom card.
For instance a
Blue Cash American Express card gives you a 1.5% rebate off of
every purchase and a 5% rebate off on purchases made at gas
stations, drug stores, and super markets. The Blue Cash card's APR
is much lower at 12.47%, but if you don't have an established
credit history you might not be approved for a Blue Cash
card.
If you can't get a better reward credit card, and you plan on
paying off your balance every month then you should apply for a
Chase Freedom card.
