For all of you skeptics out there who believe that you hurt your credit (by a lot) by constantly applying for cards, (like I do), I just got an email from Citibank offering an increased credit line on my Citi Thankyou Preferred card (a card I only use if there is a spending incentive). I said yes! to the offer. Thanks Citibank! Now send me another spending incentive so I can start using my new increased credit limit.
