I received the same offer on my Citi DP card when I logged on to Citi's website this evening -- it looked interesting, so I went ahead and activated it.
I also received this offer on my Thank You Prenier card. I activated it. I don't have any immediate plans for using it, but it's nice to have.
Nice! I received this late last year; expired this month. I wish they would offer it again.
ETA: thanks for posting. I checked my Diamond Preferred and Thankyou Premier-no offer; but they are offering the 0% on my Dividend until 1/1/2018!! Woo hoo!
