I got the WM card last Summer IIRC, and at the time it had a $300 SL. This didn't bother me too awful much as I am not a frequent WalMart customer. I did use it a few times at Sam's club and paid it off ASAP. Kind of backed oof of using that card and it auto CLI'd up to $1000. About a month ago, for funsies I hit the luv button and raisedit up to 3K.
Likewise my mother had a $200 SL and tried a few times for a CLI and was denied every time. Then after 3 or 4 months got it increased to $1000. It seems like they liketo start you low and then after a few statements let you shoot the moon.
Thanks everyone, for the personal history with Wal-Mart CC, gives me some hope!
