I've used the CardMatch tool to find even stronger sign-up offers than on the issuer's main site.
Brad's Deals Editor Mark,
Earn up to a 100,000 bonus with a pre-qualified credit card offer from CreditCards.com and their CardMatch tool. Simply input your name, address, and the last four digits of your social security number to see what card offers are matched to you. These offers are sometimes much higher than what can be found in other channels. There is no impact to your credit score for using the CardMatch tool. A soft credit check will be performed, but it will not affect your credit score. Once you decide to apply for a card, a hard credit inquiry may be performed.
