Wanted to update my earlier reply. Just called into the automated system and was increased from $4500 to $7500. Sam's Discover was increased from $1600 to $6600, automated system as well.
I opened both cards in November 2011, only used each card once, last month. And btw - Sam's increased me to $10,000. Turned around and asked for an additional $3400. I just had a baby this past September so the Sam's Discover will definitely be put to good use now. I try to avoid Walmart (because of the lines) as much as possible. But DH can get some use out of the card now that it's at a pretty decent limit.
Does a balance have to report for a cli?
Excellent question, i'm not sure. I do know that the increases came after i paid the balance(s) 2 weeks ago.
