My $75 PPE card renews this month so Citi sent me a shiny new PPE card with a cover letter stating that I will earn "2 points for every dollar spent on select categories." Next day the dreaded Premier Card letter arrived telling me about the enhancements

.
After speaking with retentions today and coming up empty (didn't use the "cancel" word yet), I'm thinking about squeezing what flight points I can get out before March 2, and getting rid of the card then.
Does Citi still pro-rate the annual fee after 30 day renewal period?
