Here are the best limited-time credit card bonus offers

The Discover it® Balance Transfer and Chase Slate® Credit Card offers are not currently in market. Some of the limited-time offers mentioned below may no longer be available.

Credit card issuers frequently run special welcome bonuses, amplified rewards rates and new promotions that allow cardholders to maximize benefits — but only for a limited time. These offers can allow you to more than double the rewards you'd typically earn on a purchase or take advantage of new money-saving perks.

With thousands of credit cards available, it can be hard to keep track of all these promotions — especially if you have multiple credit cards.

CNBC Select tracked down the best welcome bonuses and limited-time promotions currently offered.
