That is about right for Sam's and GE Money Bank. I get one every six months. Tried it once at 4 months, and it said not enough experience at this credit level. Stay at 6 months for CLI requests, and they will treat you good if you keep in good standing. I PIF my Sam's store card and my Sam's Discover. I have both since they upgraded me a year ago to the Discover. Thing is, I have two separate accounts reporting which was great for me. My EQ was barely 600 when I got the first one, now it is 704. Just be patient. Six months comes around soon enough.
BTW, when I got my first CLI for the Sam's card, I did it over the phone on the automated system. They(automated robot voice) actually asked me how much CL I wanted. I was so stunned I didn't know what to say. My limit was 600, so I said$1000, and they gave me $1000, plus the existing balance(statement had not posted yet) which was $72. That made my CL $1072. Six months later I tried the LUV button and got 1600. That's where I am now and just made 24 months. Just PIF every month and get your CLI every six months. Works like a charm for me. Good luck.
