My limits were the following:
4000 Discover
5000 Barnes and Noble Master Card
7500 WorldPoints BOA Visa Signature.
Long story short, called Discover, asked to double my limit and got it. Now it's $8000. Then called the sweet Barclays backdoor number (thanks for that!!). Asked the sweetheart to double my limit, and got it. Then called Bank of America....told them I not only wanted to double my limit, but I wanted to change to the PowerRewards Card Visa Signature. After a review and I imagine some pulls, all three are doubled!
So as of today, I have a $8000 CL with Discover, $10000 Barnes And Noble and $15000 WorldPoints, soon to be PowerRewards Visa Signature. Considering that 3 years ago, my largest CL was $500....this is pretty good!! 
$33000 in CL that I can do practically whatever I want!! Bwah Bwah Bwah Bwwaaaaaahh!!! YAY!!!!
My only crappy limits are Exxon and Target ($1000 a piece). Macys Elite Store card is $3300. I believe Bloomies is $2200, and Kays went all inactive account on me. It's ok......all of them can close due to inactivity for all I care....it's all about the bank cards. I've had 2 prosper loans totally $8000 (paid off and early) and I've had a 60-month car loan that is PAID OFF. My scores should be near 800 by the end of the year for sure....and that's with a paid off tax lien.
