I had the no-fee Citi PP, converted to the Citi Preferred. I have not used my card in a year. Called to cancel, and the retention agent offered me either:
10K bonus points for $3K spend over next 6 mos,
or,
4 bonus points/$ spent on everything for the next 3 mos, for a total of 5 points/$ spent.
I took the latter.
