With only a few days left this year you already have to have a Chase credit card in order to take advantage of these Holiday reward promos in time, but here they are:
If you spend a certain amount on your Chase card at Target before Dec 31st, you can get triple points, a free 3 in 1 credit report, or a $25 Target gift card. In order to take advantage of this you need to enroll your current Chase card first: https://www.chasebonus.com/q4/Default.aspx
Once you enroll they will also give you 500 points if you add an authorized user, 1,000 points to enroll for their online service (this means to receive electronic bills I assume) and 2,500 points to signup for the Chase Fraud Detector (a service you pay for I wouldn't recommend).
Disclosure: I am a moderator/paid staff of this site, which does have advertising relationships with some credit cards that are discussed and linked to. Regardless, anything I say is my honest opinion.
