Here's another sign-up bonus for Citi Dividend World MasterCard.
Get $300 cash back after $5,000 in purchases within the first 3 months of account opening.
Here's the Citi sign-up page
New cardmembers only.
There's no annual fee.
If spending $5,000 in 3 months is too much for you, there's a $200 bonus for spending only $500 in 3 months
Hat tip to the reader who emailed me info on this.
