Credit Card Selection
I expect two kinds of people to visit a Credit Card Selection site.
Credit card selection websites are a sham that exist to earn commissions by obtaining signup for new credit cards. The reality is the different terms, features, "benefits" and other come-ons exist only to muddy the waters and make you think you can get a better deal one place or another.
That said, you may possibly be able to find a promotional deal that saves you some money. However, I would argue you will EARN the money with all the time and effort it took to find it.
Once all the smoke and mirrors are taken away, the price you have to pay for credit is a direct function of you credit report. If you have a high FICO, a good job, no problems etc. you will get a better deal than if you have had any sort of problems.
You can read all about this sort of thing in Suzie Orman's books as well as many other places.
If parts of this game are new to your, take the time to look through some of the detail pages on the left.
