No credit card required
Browse credit cards from a variety of issuers to see if there's a better card for you.
Only way to confirm if you're getting dinged is by using a credit monitoring subscription (or a free one). CreditKarma.com is good for monitoring inquiries on TU and EQ, and I believe credit.com does (or did?) monitoring on EX. Don't trust their scores (not FICO there) but the monitoring is free.
I actually have both, but they do not update for me until next week. Guess I have to just be patient and wait.
