I got a discover card 10 years ago when I was 18 and it's been nothing but a leech on my account ever since. For example, I have put 120$ into it over the past 2 months and I have seen 20$ of that reflected in my account. The other 100$ has gone to "fee's and interest".
Worst financial mistake I've made in my life so far. I highly recommend finding a different company.
