No credit card required
Browse credit cards from a variety of issuers to see if there's a better card for you.
I also suggest paying that $140 credit card balance down to zero...and only let a $5 Discover balance post monthly (keep all others at 0).
the reason i recommend paying that $140 balance is because the limit is 300...this is putting you close to 50% utilizatio on that specific card. FICO not only looks at total utilization, but it also looks at utilzation of each individual card. By paying the card to 0, it may give you a few points boost.
