If you are planing to open a Citi credit card threw Costco you might want to rethink it. If you ever try to make a legitimate dispute with them they will not cover your dispute and I was shocked when this happened being that i charged over $400,000.00 last year on that card when they told me they could not help me with my claim. Also with their cash back on charges you need to read the fine print, and also with that they would no long pay me the $ 2,200 in cash back that I was due after cancelling the card and would not apply that credit to the balance I had on the card at the time. The only good thing about the card is you can buy gas with it at there long lines which I no long. wait for to save $ 3.00. Credit Card # ending in 1919
