The Citi Prestige Card offers 50,000 points after $3000 spend within 3 months. That’s been the strong offer since Citibank increased it last spring.
And now is the time to get the card if you’ve even been on the fence about it. There reporting that the signup bonus for the Citi Prestige Card will be changing tomorrow. I don’t have any direct information on what the new offer will be, but it seems like you’re going to be much happier signing up now than you would be waiting.
