Like some of its competitors, Capital One is offering credit card deals for Cyber Week.

From Black Friday through Cyber Monday, or Nov. 25 through Nov. 28, Capital One rewards customers can earn additional rewards when they do their holiday shopping through Perk Central, Capital One's online shopping portal for rewards cardholders.

About 40 merchants will be participating in the online promotion, including Macy's, Barnes and Noble, Microsoft, J. Crew and Lands' End. Many merchants will be doubling their existing rewards offers with bonus earnings as high as 150 percent, says Sukhi Sahni, a spokeswoman for Capital One.

After the Black Friday weekend promotion ends, Capital One customers will be able to earn up to 15 bonus rewards per dollar spent with select retailers through Perk Central during the holiday shopping season, Sahni says.
