I currently have decent credit, but not exceptional due to limited use of credit. I have two credit cards, one used regularly (and payed off every month) and a backup credit card.
I've run into offers to save 50 dollars (or similar) if I apply for a credit card. Assuming I check the fine print and the discount can be received without too many restrictions; I'm wondering what the affect would be on my credit score to accept the card just to get the discount.
If I get the card and immediately close it will that be better or worse then getting a card and keeping it open but unused? How can I compare the affect on my credit to cold hard cash?
