I have Discover as my only credit card. I do generally ask if places take Discover but I can't think of a time where I've tried to use it and got turned down. I don't really buy much on it. I guess it couldn't hurt though since it's 5% back on specific categories each month. Like this month it's on restaurants, gas & hotels. Up to the first $300 you spend there though. I think maybe they give 2% of purchases in general too. Well shit, maybe I should do that....

I dunno, just not really in the habit of buying shit on credit when I have a debit card and plenty of money in my checking account. I really only use the credit card for bigger purchases that I want to get a chance to plan to pay for. :dunno:
