I paid off my FCNB and my First Premier accounts. I made sure they were -0- balance and closed them today. I actually will be getting $9.13 and $3.79 back because I overpaid (hmmm). I am now in Prime land and will never need their piddly $150 and $300 limits again. Oh the funny part....when I called FCNB to close, they told me they raised my limit to $200 yesterday haha.
When I was ready to close my 1st premier acct. I called and was transferred to retention. They gave me a substantial credit line increase, decreased the apr to 9.9% and waived all fees permanently. So I kept it.
