Well i just paid off the card completely and i don't even use it anymore. The $300 is not worth the headache, I didn't close it, but i'm just not using it.
The thing is I would rather not even have to deal with this entire CC stuff, thats the reason I didn't get one in college, I saw what it did to some of my older family members and was warned against it. But now I'm realizing that paying $400-600 a week for a flight and hotel is too expensive to use against a regular bank account, even if you get reimbursed after the fact.
