GEMB has been good to me with CLI's too!
Congrats on the bump & keep up the good work.
In order to reduce my utilization ratio on my Chevron/Texaco card (part of GEMB), I asked for a credit line increase online. I have had the card for 6 months and they instantly bumped up my credit limit $200 to $650. I still think that is really low since one fill up uses about 6% of my balance and I want to stay under 10%. But hey, a credit increase is a credit increase and I'll take what I can get. Woohoo!
Did they do a hard pull?
