Congratulations! I've heard rumor it can go to 4k. Ours sits at 3k and my DW puts light spend on it.
Congrats again, keep pushing it!
Unfortunately, there was only a very brief window in the summer of 2017 where Capital One was allowing increases to $4,000 on the Kohl's card and a few of us here were able to get that increase. There is one member of the forums who has a $5,000 Kohl's limit, but IIRC her limit was already at that amount when CapOne bought the portfolio from Chase about 10 years ago. Anyone with a $3,000 limit who asks will get a denial letter stating "You already have the maximum credit line that this type of account allows."
@SUPERSQUID congrats on the increase. Looks like you are on the typical 300-700-1500-2500-3000 pattern for this card, so smash that button again in about 6 months and hopefully we'll see another CLI thread celebrating your new $2500 credit line!
