I have had my cashRewards card for a little over two years and my GO Rewards card for a little over one year. I asked for an APR reduction and both were lowered to the lowest rate they offer.
I figured I was in good shape to try for a CLI on my cashRewards card so I asked for a 10K CLI. It was a HP on EX as expected since it's my only report not currently frozen. Got the 24hr message and checked this morning to see that they raised my limit from 25K -> 32K. No complaints here and also no POI required. This was my first CLI on my cashRewards since it started at 25K
My GO Rewards has grown from a SL of 5K -> 22K -> 25K via SP CLI over the year or so of having it.
Very nice! Congratulations!!
